A 102" stainless whip is nothing more than a quarter wave antenna when it's working against a proper ground plane. It has unity gain. The highest gain vertical for CB use is the Sigma 4 design, it is a full 3/4 wave and will offer a solid 3 db or one half S unit over a quarter wave. Doesn't sound like much but you have to double your power on the quarter wave to equal it.
My guy the mower J. You can just tell he's a lovely man. Love from London
Yah , I had questions about that myself .
And now that you’ve answered that question , let’s get at it ! Copper is definitely better than stainless steel !
But um , sir , what kind of trouble do you have with lightning ? Because I took notice , you didn’t ground it .
I talked to a fellow ham in Panama City on 10 Meters with a 102" whip and a mobile rig.
Now I see why the same amount of Copper cost more than stainless steel ! Good comparison video 👏👏👏
I'm a simple guy, I see a Mower Junkie video pop up I watch it. :) 697 Nashville, T.N. 73
Thank You so much! I really enjoyed this comment. Take care 697, 73's from 151 SC.
You should make them and sell them with all necessary material
The video showed you got 1 DB at 12 miles and a 9 DB at 12 miles with your home made Antenna ????
431 top of the Rocky Mountains here in Montana listening for you. Rock on bro!
Copy that 431. Happy holidays. 73's from 151 SC.
My vertical 102" 10 gauge copper wire antenna is held up by a rope tied to 2 trees 40 feet high similar to your PVC setup but mine has four 14 gauge copper radials sloped at 40 degrees. I can regularly chat with a few distant CBers on CH 38 barefoot about 50+ miles away.
Propergation changes can occure over a few minutes and effect signal strenth significantly . IF you live in a extended rural area the noise level my not be a problem but in Urban areas is often a S-7 +. At legal power , cb in my city is often limited to a mile because of power line noise .
That sucks! I'm sorry You have so much noise. I don't have much noise on My radios, not even the one in My car. So for Me to get these test done, I have to go at least 12 Miles away. Thanks for watching, Take care.
A good comparison there John, definitely a lot to be said for home made antennas.
Didnt get chance to work mine weather pretty crappy here in UK all weekend. Stay safe man 337 waving.
From the movies I feel lile it is always raining in the UK.
Sorry to hear that Paul. I hope You have better weather coming. Take care 337, 73's from 151 SC.
Best ground plane for omni gain is the. .64 wave. The vertical element is about 22 feet long! 3 or 4 ground radials.
Check out the Sigma4 design. They are no longer made by the Avanti company, but the Italian company Sirio makes a clone that works as well. 27 ft tall radiator gamma fed at the base with a halo at the bottom. It's a full 3/4 wave antenna that just flat out performs.
Had a Jo Gunn 4v on a 30' tower with about 1200 watts @ 26.935 and talked from central Indiana over the west coast to australia for about 15 min.
Used to do that every night during the late 1980s running a President HR 2510, 150 W Cobra 150 Amp into a 96" Francis Amazer on the back of my Hyundai Excel.
That's pretty awesome. A few dollars in materials and some sweat equity beats most high end antennas.You might consider building the next one out of 8 gauge wire just to see if there's any benefit. Thanks for sharing.
I followed your other Video, built a copper one. It was so exciting to hook up the swr meter and watch that needle fall to the bottom and sit. Now if I could just get some local guys to do the same. Seems like most of them are hams. Thank you two for the great vids
Use copper tubing....more receive.
@@smg8498 works pretty good. But I feel like I need to go up another 10’. The base of the wire is at 20’ right now.
@@smg8498 copper tubing instead of wire? Hmmm... Better receive ? Because of the size of the copper? I made mine out. Of no. 8 wire I had laying around. People say its not bad, and could be better. I have 4 radials on it also, my. S.w.r. is about one to one. I d. Like to her them say it sounds damn good.
Great video, I enjoy the way you present a problem and use science to test it. The outcome does not always come out like one would expect. It's great how your wife enthusiastically helps you with your projects. Looking forward to you next video!
Thank You so much. I have a lot of fun, doing My part to keep the hobby alive. Thanks for watching, Take care.
1/4 wave antenna is great for skip. Need a 5/8ths wave GP for local!
151 I just wonder if the ground elements is what made the difference in the performance cuz the homemade definitely sound awesome
Add more ground plane radials, if you can add another 1 or 2 radials it’ll improve your local reception.
You can also change the feedpoint impedance by changing the angle the radials run. Sloping them makes the antenna closer to 50 ohms but it gives less low angle radiation for DX. Running them flat at 90 degrees makes it DX a little better, but you will need a matching network to correct the impedance mispatch, the antenna will be somewhere around 27 ohms.
You need more radials. The signal is going to focus on the direction of the radials.
well mower mower junkie i done it! i finally ordered the tram and all the fixings! should be running proper in a couple weeks!
Awesome! I can't wait to hear how it works for You.
@@MowerJunkie just got the tower down to do some work on it befor the coax and pl259s get here! i alos checked the contents of the box when the antenna got here and they had everything in there!
I plan on making a ground plane based of of the Macon v-5000 but with all copper tubbing. Wish me luck. Lol
The White PVC pipe you used is not the best RF transparent you can get. If you had used gray PVC for electrical conduit, it would be more transparent. Simple test can be done. Chop equal pieces of both and place each one by itself in your microwave oven and operate for 60 seconds. Measure the temperature of both and the cooler one is RF transparent. SWR and range will be better for the most transparent one used.
It all goes back to the old adage, the more metal you got up the the better it will work!! An antenna made of copper pipe would work even better! (you would have to coat it to keep the corrosion down.
Great stuff as usual. just an observation, I noticed there is a bit of distortion on AM on the Washington. Someone may have removed TR23 (2sc945) which is the AM only modulation limiter.
I'm not sure why, But it only sounds like that when My Wife uses it. When I use My Washington, it is clear on SSB and AM. I'm going to setup a ceramic mic for Her to try. Thanks for watching, Take care.
President madison with extra switch was the best transeiver i ever had, I got to get into 11 meter again
Love these tests. Thanks to Mower Junkie
I like watching your videos but I could never hear you that good
All my newer videos are louder. unfortunately I can not change the old ones. Thanks for watching, 73's
@MowerJunkie I love all your videos very big fan God bless and merry Christmas 🎅 🎄
Radials are everything, assuming the whip had none, and the wire had 2,,,,,,,,,THATS why the wire antenna, performed better,,,,cool vid,,,add more radials, and the performance will increase,,,,de NV1H😎
Good test Mr and Mrs mower junkie hello from hillbilly in the bam I've been working on a using two ss whips just a little twist
Thanks Hillbilly. let Me know how the 2 whips work out, I'm curious of how well it will do. Take care, 73's from 151 SC.
I'm totally lost about base station antennas. I've always had mobile radios and used magnet mounts. They have always worked great for me. But I got a bunch of local guys on bases around here and i can't hear some of them well or reach some of them. They are great guys and I'm so glad I have so many locals still using CB. But I need a base station so i can reach them all. On my mobile sometimes I can talk to one of them almost 20 miles away but it has to be a quiet day with no skip coming in or noise. Other days they can't hear me at all and I barely hear them. The closest guy is about 10 miles away and we can talk clearly all the time. So I don't really need power....i need a base antenna
I'm running a galaxy 959 thats peaked and tuned and does 32w pep and 14w bird average. It talks 20 miles on a good clear and quiet day so I got enough power for now.
So here's my plan and tell me what you all think. I want my radio in the metal barn I have. My shop. It's about 40 foot long and all metal. I'm thinking about buying a quad magnet ( 4 magnets) and putting a 102 whip on it. Stick it on metal barn roof and see how it works. It should act as a ground plane like the roof of my truck does. Do you think it will work ok?? It should be a HUGE improvement over my Mobil truck antenna which is a little Wilson. I just don't understand how to make a normal base antenna work. I suck at electrical wiring ext.
I'm tired of sitting in the truck to talk with my local base freinds. I need a cheap and easy solution. I'm hoping this idea works
Very nice comparison. 7351 and good contacts. The winner is your homebrew base antenna congrats.
CAROLINA FOUR BARREL ON THE COAST OF NORTH CAROLINA GOOD WORK MOWER JUNKIE STAY COOL
Great video dude!!! The results were pretty conclusive. Was your home made antenna a T2LT design?
Thank You Simon. Both antennas were a simple 3 wire Ground plane (1 vertical, and 2 down at 45 degrees). Thanks for watching, Take care.
@@MowerJunkie are you saying both areas were exactly the same as in both quarter wavelength long and ground plane. The only difference being the second one is copper wire and the first one is stainless steel?
Although the swr readings are within acceptable rage for both antennas. I wonder, if the actual resonant length of the pvc antenna (which would have a better swr reading) made the difference in the range of transmit vs. the material the antenna was made of. Great video. Thank you for your time and effort!
I wondered the same thing! Because lower SWR = more power out. Thanks for watching, 73's from 151 SC.
What are the details on the ground plane on the copper pipe? I'm trying to build one like this and getting all kind of conflicting answers on how long or if they are even needed at all.
Love the video mower junkie?
Thank you so much for this video. I've been doing tons of studies on antennas lately and your test was an eye opener. Up to this point I had considered antenna design and feedline as points for loss, but had not even thought about the actual conductor used being a loss factor in the design. Seeing the installation I can see the dilemna why you are restricted to using 2 radials, but would be very interesting to see how 4 radials would improve the range. Another thought is have you considered changing the two existing stainless steel ground wires over to copper as well? I suspect this alone without adding two additional ground radials could possibly increase the efficiency slightly more?
I may have misread the description...are the ground radials already copper? Sorry if I misunderstood.
the stainless steel whip has SS ground plane wires, and the Homemade antenna has copper ground plane wires. In the future I will try the SS whip with copper radials, just to see if it makes a difference.
awesome bro so relaxing to watch you and your .5 on here happy TXing kh348 New Zealand plus i also have my homemade full wave on the tree i have a rope hanging from the tree the tree stands about 70ish feet tall and i use the rope to hoist the aerial up and lower it down when high winds hit plus easy maintenance it works for me try it give it a go and see if does good for you
Thanks for sharing, I might have to give that a try. Thanks for watching, Take care.
your welcome
How long were your copper wires? And how well does it perform without the linear?
Just started building one of my own! Hope it works. 1220 northern indiana.
Awesome! I hope it all works out. Take care 1220, 73's from 151 SC.
@@MowerJunkie I finished the antenna today! At first when I hooked it up there was nothing coming through the radio even with the volume all the way up. I then realized that the antenna needed a ground plane after watching one of your videos. I have grounded the antenna and will test it soon. 1220 northern indiana.
I don’t know how I missed this video a few years ago 🤷🏼♂️
Very surprising results
I bought quite a bit of material at Home Depot last week
The antenna building bug bit me
I’m wanting to try a 102 inch hollow copper water pipe , and some ground radials . Possibly at the bottom, use a short piece of pvc pipe to isolate it from the antenna mast . Have you ever experimented with that setup ?
Thanks Dallas. I haven't tried copper pipe as an antenna, keep me updated on how it works out.
I need some help. Due to HOA I can only put up a vertical dipole using two 102" whips out of my second floor balcony two feet out ( it is a three stories townhouse). I know this is not ideal but that all I could so. My question is I have very high SWR. Being a dipole I did not ground the antenna, the hot goes to the up whip and the ground from coax goes to the down whip. I did not add the 4" heavy duty spring that is normally used with 102" whip. Any idea how I might improve the SWR?
try moving it out a little more, it should be 3 feet or more from the building.
@@MowerJunkie I can't not move the antenna any further out. In my situation, a three-story townhouse with a balcony on second floor and with houses connected on my left and right and a HOA. Any suggestion as to what antenna I can use? Much appreciated for your help.
I have no interest in DXing but...
I use a 20ft piece of PVC pipe and Ive wound 36ft of copper wire left over from my home rewire. (like a firestik) Works great out to around 20 miles. SWR 1.2, 20ft in the air.
I also use a 36ft copper wire dipole strung down the garden just higher than the washing line.. Works better than expected but only in 2 directions. SWR 1.5
When the summer comes I may take the dipole down and use the wire to make another pipe Firestik and use it as a ground plane for the me made Firestik and see how that works.
From my experience.... Homemade is always better.
I agree, Homemade antennas are more fun, and have a strange satisfaction when they work well.
I recently tried a fiberglass whip, maybe 2.5 feet long, with an 8ft something copper wire to make it a dipole, vertical. Attic mounted.
I had a contact 35 miles away over mountains. Just 4 watts.
Are you using the 36 ft of copper wire on 27mhz? If so, something unusual is going on because a full wavelength antenna doesn't radiate. It will only warm up - depending on how much rf energy you pump into it..
Get a 49:1 balun and rig up a 1/2 wave vertical with wire (or pipe and whip)...bet it will beat out both of those.
Why not use a 1:1 balun?
The EFHW antenna (end fed half wave) has a 2500 ohm impedance. A 49:1 balun allows it to match the 50 ohm load requirement of the radio. Without the balun, the SWR mismatch could damage the radio.
I paused the video to watch this. Somehow I think the thinner, copper will radiate the signal better than the steel. An actual wire never seems to straighten out completely no matter how much tension I might put on it, there always is a wave to it, and I've wondered if this could distort a signal. The steel whip, being thicker, will be straighter along the length. I know nothing about the physics of an antenna, however I always wondered if straightness was at least one factor. I be interested to see a comparison of the same dimension aerial, one copper and one steel.
I use 12g solid copper wire, and it's pretty rigid. a little bit a wave in the wire won't affect the function of the antenna. Thanks for watching. 73's from 151 SC.
I've made a quarter wave antenna but I can't get the ground plane wires right i end up with 60w on channel 1 and slowly goes up through the channels to 100w.
Any help most appreciated
😀👍 Very good Antenna Show!
It looks like you've got the homemade antenna higher in the air? Either way there is definitely a huge gain.....
You are correct, the Homemade is a little higher. Thanks for watching, 73's from 151 SC.
Height is everything for line of sight/local... Ten feet makes a difference
I'm personally fighting with the idea of building one or buying a beam 🤦♂️ I'm afraid we're hooked bud lol 73's to you and yours
I think You should put up both!....Ya, I'm definitely hooked on the hobby. Thanks for watching, 73's from 151 SC.
I would love to see a vertical 11m half wave endfed with 49-1 z transformer comparison. Thrown in a tree.
Nice comparison! 12 miles is a good distance away. What is the terrain like, mostly flat or hills?
Thank You. it's mostly flat here with a lot of trees. Thanks for watching, Take care.
How is it even possible you can do that i'll tell you this much i would give anything you make the antenna and I'll buy it
both sound excellent.73 151 from kb3aum im gone.
Thanks for watching, 73's from 151 SC.
Now you have to do some DXing ! I built many a 1/4 wave Copper Tubing CB antennas & they all worked great but never thought about using pvc to reinforce the soft copper. Are you using copper wire inside the pvc? 1/2 wave?
I have been messing with c.b. radios for around 25 yes. I have copied a few antenna designs, and like you I always think ... But what if that antenna works better? My question to you is ... For a 102" steel whip , antenna only... How can there be a difference , and the fluctuation of the price for what looks like the same thing !! ???? Is one better than the other in a steel whip ???
Not exactly a fair fight.. 1:2 against flat and SS against copper. I'd like to see a homemade silver antenna against copper fight !!
LOL, If You send Me the silver, I'd be glad to test it for You. Thanks for watching, Take care.
@@MowerJunkie I've thought about it . You can get serling silver which is 92% silver and 8% copper at 16 guage wire for 5.70 a foot. A half wave (18ft) would run 102 bucks.A 1/4 wave for 51.

Awesome video. Built a similar antenna to yours, and have spoke worldwide on it. Is there a link to your antenna build so I can get my swr a tad lower? It's sitting pretty damn low now. Was considering switching to a 102 but guess I won't now. Also.. did you run the same ground planes with the 102 in the test?
Awesome videos. One of my favorite channels.
73's to you 727 central alberta Canada
yes, I did use the same ground plane wires with both antennas. the best way I've found to adjust the SWR with this type of antenna, is to adjust the angle of the ground radials. they can be between 30-45 degrees. sometimes 30 works best, sometimes 45 works best. give it a try, it could work for you too. Thanks for watching, 73's from 151 SC.
can you upload a video with a comparative betwen newest CB Transceiver like President Bill and the old goods transceivers uniden etcetc (in AM mode). Your channel is my favorite!!! Best wishes ! Regards from Buenos Aires Argentina!
Thank You for the comment. I wish I could do a test with a new radio.....But I don't have any new ones. My newest radio is about 25 years old. but if I get any new radios, I will definitely do some range testing with them. Thanks for watching. Take care.
Great vid and inspires me to make my own antenna however I was slightly distracted by those tasty looking doughnuts, come on sharing is caring :-)

I think in another video the Whip has beat the dipole so ground plane is king?
Were both ant grand radials set at the 45 or was one horizontal 45 give the reflective a bit more umph similar to a " starduster,," the horizontal reflects up and 45 reflects horizon giving better swr response good test

it's all in this video. czcams.com/video/6DNIpUZvI2k/video.html
So do you have a plan of the new antenna?
I must ask... were you using the 2 wire radials in each test for BOTH antennas?
Yes, the 102 whip had 2 stainless steel 102" long ground plane wires. and the homemade had 2 12g solid copper 102" long ground plane wires.
So how much coax cable did you use on it
50' of rg8x
i don't no if anyone has told you but you need your mic closer to you when your making a video

@@MowerJunkie AWESOME💕💕💕
I keep making one like yours, but when I put it vertically its SWR is crappy. I have the bottom of it sitting on the ground, and the antenna part in the air at 16 ft. Does it need to be in the air higher to get the SWR down, or should I add a ground wire to bond it?
Needs to go up free of ground 9 to 15 ft for good testing 9 because is quarterwave separation from earth
@@billbowman5738 ill just have to make it into a horizontal in my attic instead. Cant get it into the air as i dont have the space. Oh well thanks.
@@troydhansen4990 have you been using RG 59 for match I'll look up length but a piece 75 ohm cable and then the 50 ohm feed line usually brings down
the angle and number of the ground plane radials can change your swr reading too.
The ground plane radials should be connected as close as possible to the feed point of the antenna. I usually connect My radials directly to the antenna mount.
Ok ,so the homemade pvc and wire beat the 102" whip,and if i remember correctly the pvc antenna beat the tram ,correct?
I haven't tested the Homemade against the Tram yet,....But I will!

Thank You so much Adam! I appreciate You being here. Take care, 73's from 151 SC.
to be fair rerun the test without the black box and test the swrs with the base radio! the antenna might have a perfict match with one radio but different on another
I put the SWR meter in line with the Washington too. With just the radio, the SWR was the same as it was with the Realistic. the 102" whip with the box on has an SWR of 1.3 to 1, and the Homemade with the box on is just under 1.2 to 1. I used the Realistic to test the Homemade antenna, just so if the antenna had an issue, the Realistic would take the beating instead of breaking My Washington.

Do I need the pvc or can I just run copper wire?
The PVC is needed to keep the center element upright. the wire will just fall over without something holding it.
You could run the copper up a tree or a flag pole if you have one, it doesnt have to be PVC...
Be inventive and use your imagination.
ho long the copper antenna 102 inches ?
Yes, all 3 elements are 102 inches long.
Is there an on line calculator i can use to figure this info out?
468 ÷ frequency in MHz. Will give you overall length.
So for 27.2 MHz (the middle of the band) it would be:
468÷27.2= 17.2 feet, or 206.4 inches. That's about 103.2 inches per side.
It's always best to start out a little higher and trim as necessary. And adding a choke coil is very highly recommended. 5-8 wraps of coax at the feed point, around a 4" piece of PVC is good for 27 MHz.

Put your 102 in still whip on top of your Antron 99 cut it 2 length of the normal length of the top of the antenna of a Antron 99 and see how good you get out then
No need to cut anything, use the rings for fine tuning. If I'm not mistaken it puts it closer to the "I-max" that is "5/8s wave {insead of 1/2}and more broad banded. the only downside is when ice forms it can cause heavy strain on the middle.
I have been in the radio hobby for over 45 years. I've tried every vertical made for CB. Nothing touches the Sigma4 or the clones made today. They are a full 27 ft tall and fed at the base with a gamma match and they have a strange inverted halo at the bottom....but they kick ass! I guarantee you, they out talk and hear any other 5/8 or fiberglass antenna in the CB world. Next best are the Sigma 5/8 clones or the Hygain Penetrator clones. But they have radials, the Sigma 4 clones do not, much easier to put up.
@@richb.4374 Thanks for the input.I will check them out! I have been a CB pirate for 30 years and the best setup I had was a 2 element beam with a 5/8s "I-max on top 10 feet that said couldn't be done{no standing wave problems} 30 feet at the bottom element 3 years before a storm got it. {"The Wanderer" 113} Central NC. not too far from "Elkin" if u know anything about that.

Can't hear you Nice videos

Where is your 4 ground radials??? ALWAYS 4
The famous Star Duster only has 3. more is better, but 2 will work.
@@MowerJunkie 4 is always Optimal! higher SWR with less.. But again that company can make more money selling less radials.

Thanks for watching, 73's from 151 SC.
I need someonw to help me make a homemade antenna
Try making a Dipole, it's an easy one man project.
Thanks for watching, 73's
Range test.
Thank you.

Its all about the angle of radiation..... For local talk you want to keep your signal closer to the ground but for Skip you want it to point up. This is why a horizontal dipole works very well for long distance contacts as the signal is pointed straight up bouncing off the ground. This is also why the type of soil you have plays a big part. run some ground radials into the water if you are by a lake or ocean and see what happens. muahahahahha.
This is why I use ground plane antennas. At 3/4 of a wave length up in the air they have an interesting wave pattern. it looks like a doughnut on top of a doughnut. So it will do just as well for skip, as it will for local. Thanks for watching, Take care.
