Great video. I have both the Wolf River coil and the Gabil but have never done the comparison that you have now done. So thank you. I have been impressed with the Gabil's performance for such a small "compromise" antenna. I now am using it indoors in my upstairs office on the Wolf River tripod, and using a single ~17' radial for 20 meters that's just a wire stung down a hallway. I've been amazed that it has worked so well. You've inspired me to hook up my WSPRLite device to try to get a comparison between the two antennas in indoor use (HOA restricted community).
Al, I would be interested in the results! Operating in the house / hallway; no HOA gonna stop us! I wasn't aware of this WSPRLite device; now I hope to get my hands on one--no stock anywhere in the world right now.
Like that cable junction box.
Thanks Will, pretty proud of how that turned out. One of these days, I'll need to do a video with that as the focus.
Thank you! We need MORE videos like this. 👍
Thanks David for the kind words.
@@HOAHamRadio Seriously...I wish more professional youtubers would adopt this style of direct "A vs B" comparison, rather than talking about a product which was sent to them for free or discounted price, and saying "it works well". This video was very well done.
Hi Bob, I also have the WRC silver bullet 1000 TIA and the GRA-7350TC. Like you I will never part with the WRC, but purchased the GRA-7350TC as it breaks down to less than 12 inches. I ordered the 3/8-24 version of the GRA and can also use it in the WRC base. I also use both antennas in a mag mount on my truck. I used my vna to make a chart for the GRA from 80m to 10m and do a quick check with the SWR scan on my X6100. I have had fantastic results as well. I have also used both antennas with window screen and Faraday cloth with the WRC base. I have been trying bicycle mobile using a mirror mount on the handle bars, 18ft of RG-316 and the GRA-7350TC with and without a counterpoise with the X6100 on 5 watts. I ground the bike frame to the base and again had great results. The counterpoise did not make a change. On 20m I use a setting of "4" in the mag mount while "4.25" works on the bike. The GRA-7350TC goes in my backpack with no trouble and works well. Tim, VE3VTH.
It's quite surprising isn't it; an antenna this small works so well. Thanks for sharing the detail of your experiences.
Great video. I’m new to ham radio, and I tend to suffer “paralysis by analysis”. You doing comparisons like this help me immensely, and you have done all the analysis for me.
Thanks for watching The Bugkiller and offering feedback. It can be intimidating with all there is to learn and understand. I've learned mostly through trial and error and try to pass that along.
One of the best features of Gabil coil (as well as MFT 1898) is the ruler. It can be tuned in advance and the position numbers written up, then during field operation it'll take literally seconds to jump between the bands. Thanks for the comparison and 73!
@Alex_556 for sure, the markings can be very helpful.
Thanks for the comparison. Really love the size of the Gabil antenna.
They perform amazingly well for their size. Thanks for watching and commenting.
Thank you for the great video comparison! Please consider commenting on durability once you have some more time on the Gabil.
M617, that is actually the final part of the comparison that is important to me as well. Expect a follow up in a few months, after I've put it to the test for a longer period of time.
Great comparison of two great antennas Bob. Well done !
Appreciate the positive feedback. Both are fantastic options!
That was really cool. Thank you for comparing the two verticals. I like the sleek factor of the Gable. I may have to get myself one.
It is a really sleek antenna, and I'll admit, it has surprised me on performance. It still needs to be durable for its use case; i.e., portable set up, over and over and over and over... I'll do a follow up video.
Thanks for the video. I’ve tried the Gabil. I do like the stand, very versatile. I do like how light it is and compact. But I prefer the WRC over it.
Tim, the WRC just gets the job done; it is an awesome system!
@@HOAHamRadio true, very true.
Thanks for the video. Very interesting and great job comparing the 2 antennas.
Thanks Bob for the feedback. I try to compare gear as often as possible; it helps us all think through the details, options, and differences with a frame of reference.
I have the Gable on order for Wednesday delivery. After your results, I’m very optimistic that I will have somewhere results as well. I have the first Jen Wolf River coil and it always causes me a drama whenever I use it. I’m glad to see it’s probably just me and not the intended that’s got the problems. 73’s
I'd love to hear your feedback once you've had a chance to use it a few times. I like it a great deal so far.
I enjoyed this comparison video 73 KV5P
...and I enjoyed doing it. Finding the best gear is one of my favorite activities; thanks for watching.
Grabbed one after your first video. I like it. I MIGHT play around getting it on 60m for fun.
Thanks Don for picking that up off my affiliate link. Let me know how it performs on 60.
Nice job with the comparison 👍
Thanks Ape, this has been one of my more enjoyable projects.
Awesome test. thank you for the information.
My pleasure. This tiny antenna works surprisingly well!
Had a WRC fail today. Due to weight of WRC I will be going to Gabil.
Hope you enjoy it kylefreemason. Because its size and performance, it is one of my favorite antennas.
@@HOAHamRadio I think I will. Definitely going to enjoy the weight and slim design.
Good video, would LOVE to see a comparison on ft8 and pskreporter
I’d have to learn those tools / skills first. Four + years into my ham way of life I’ve learned a lot, but there’s no end in sight. So much ham so little time.
Thanks for the video!!
Welcome. I’m enjoying putting the Gabil through its paces.
$260+ for that Gabil antenna setup. I'll take the Wolf River for half the price.
13 Colonies was such a pain from the west coast but I gott’em all.
Nice job. I've not let myself make that a goal yet. I have a touch of OCD so once I set my sights on something, I just can't let go.
On the gabil gra 7350ot antenna and gabil tripod may I ask what length of counterpoise wire is required for operation .
Ground radials depend on many many factors and vary form location to location. I use three 16 1/2' radials and this gets me acceptable SWR 17 -40; which is where I hang out.
Good luck brother!
Thanks Psyops. Gotta get this hurricane out of the way; I've got some cool videos coming and this thing is wasting my time.
This is good content. I'm curious to see someone comparing the ultra expensive chameleon mpas with the fair priced qrpguys efhw.
I know the result but I'm curious to know if other hams get the same results
I like to compare head to head when possible, while eliminating any many variables as you can control. Now you've made me want to compare the MPAS 2.0 vertical to the Gabil.....
Great job I'm in a apartment building as all know I. Looking toward the eolf River coil the 500 watt version for 20m 40m looks like it's ago
You can't go wrong with the Wolf River Coil. I wasn't aware they were working on a 500W unit; that will give us another optoin.
Yes it's been out there's a version that's bigger and that handles 500 whiskies. Check into it. Thanks friend 73s
Very nice introduction 👍💯💯
Thanks ATOMS, hope you are doing well.
@@HOAHamRadio yes sir thank you 73s 👍⚛
Thanks for the video! How much power were you putting through the Grabil? What is it rated for? I'll have to look it up but its nice to see you you can bust through pileups and the qrm. Cheers and 73 de W3LAM
Thanks for watching Lam The Ham. It is rated for 100 watts SSB voice, and that's what I was sending through it.
Great video. Do you remember what length you were using for radials on the Gabil?
Yes David, I use bundles of 3 radials, 16 1/2 feet per radial. Here's my video on my radial system -- czcams.com/video/pTNojRg8x40/video.html
Great review of the 2 antennas.
KK4CWO Jim
Thanks, appreciate you watching.
...thank you very much for this fine antenna comparison video! I´ll buy here in germany the HF-Pro-2-Plus-T for my portable activities.....
I was searching a long time for a video like yours, so a special thanks for this comparison...
73 Mike DO1MDE
Michael, you'll be happy to know the Komunica is exactly the same; I own it as well. Awesome antenna! Thanks for watching.
Great video, thanks. Thinking of new toys when I retire x2. Very helpful. 73, KF0NNQ
My pleasure. Lots of great gear and options out there.
Great video!
Thanks Shane. Just subbed to your channel and learned about linear dipoles!
@@HOAHamRadio I thought I had subscribed already, I am now.
Another great video, what is in the background in your shack. Is that a SDR radio screen or a program of some kind. Also, when turning the antennas was that ant analyzer you were using. On mind I need to be 20 ft away to get a good reading.
Clifton, the background is SDRUno running on my Windows 10 PC, connected to a RSPdx receive only unit. In addition to giving me an incredible view of the waterfall, I have rig control.
I use an MFJ-223 analyzer; I just recently picked up the RigExpert Stick Pro and will be migrating to it....once I become an expert on it.
Sending my GRA-7350T back to Amazon. Within a day the scale is falling apart where the clamp grips. Same issue as seen on another CZcams video. This scale needs to be laser engraved on the tube not a piece of tape! Since they took your last suggestion, would you bring this up with the manufacturer?
Randy, I really appreciate you bringing this up. If people are having issues, its helpful to make me aware. I only want to talk about gear that is reliable. This is certainly an issue and I will relay the concern to Gabil to see if this is a problem more common than I am aware. You mention a CZcams video that covers this issue; would really appreciate a link so I can also send that to Gabil.
czcams.com/video/LS17tVl3F0U/video.html
Hope that CZcams will allow the link in the message!
Yep, its working. Thanks for passing this along. I will advise Gabil of the issue....seems like this has been an issue for a few people.
I just want to add I'm not dissing the antenna I really like it except for how it disfigures the calibration label on the inside when you tighten down the ring. If they would go to a laser marked scale it would eliminate the problem completely and be very durable. A fine antenna otherwise. Except for that issue, a very good design.
Well, wouldn't you know it, they sent me a sample......anodized and engraved. I tour it apart, and the RF connection is on the inner tube so it is not affected by the anodize. Based on this new design, it seems perhaps they were getting feedback for several people with this label issue, so thanks for speaking up. The new version just recently went live on Amazon. It is a win anytime our gear gets upgraded!
I really enjoyed seeing the antenna comparison. I was wondering, what radio and TX power setting were you using for the comparison? Thanks, Bill. KC2KNA
Thanks for the view and feedback. I was running my Yaesu 991A with 100 watts.
I received the Gabil today, I noticed that the threads are not 3/8x24.. What threading is that? Wanted to thread the Chameleon whip into the 80m Gabil coil and see what happened but it wont fit.
I'll check into that; your question makes me want to experiment as well. Thanks for asking.
@@HOAHamRadio I think it might be 10x1.0mm What a drag.
@HOA Ham, from where did you get that clamp for use with a picnic table?
PolyMath, thanks for watching. Here are affiliate links to the picnic table bracket, the small ground spike which is the top I used on the picnic table bracket, and some adapters:
amzn.to/3AQnLCa
ebay.us/9Xms8D
amzn.to/3THppi2
I'm already sold on the tripod, and you're persuading me on the antenna. The combo seems exactly what I need. How about a mag mount comparison for (parked) mobile ops? vy 73 de WZ9U
Getting it onto a vehicle some day is on my list...lots of stuff on my list.
Great video, just curious what antenna analyzer are you using to check swr?
I use the MFJ-223. I’ve recently purchased a Rigexpert Stick Pro and will be migrating to it once I become better acquainted with it-I need some of the advanced features it offers. The 223 has always worked well for me.
Could you tell me the name of your entrance box you have on your house please ? Thank you
It is a DX Engineering kit; here's a link www.dxengineering.com/parts/dxe-ue-2p
@@HOAHamRadio Thank you
I like your video. What is the part number for the 80 meter coil? I looked on the Gabil website and I do not see it listed. Thanks
Fred, they don't show it or put it in the description, but it comes as part of the GRA-7350T system.
@@HOAHamRadio ok, I couldn't find anywhere that stated that it came with the system. Thank you!
What would you recommend for a base for scanning vhf and air band
RI-928, well, I don't have experience on this one.... I know others recommend using a discone antenna for this type of scanning. Here is one that Gabil sells, but again, I don't have experience on this subject: amzn.to/43FPfr5 Maybe search CZcams for best antenna for scanning.
@@HOAHamRadio thanks for getting back to me ! I’m scrolling through the usual places and trying to educate my self
@@porsche928ireland There's a ton to learn and experience, and I've found it to be a fantastic journey.
Bob, do you think there would be any benefit at all to mating the BD7IBI whip with the GRA-7350T base loading coil for use on the 10M-80M bands? The BD7IBI is sufficient resonant on 10M alone so the combo seems like it might offer an opportunity to 1) maintain fully portable multi-band POTA setup, and 2) an improved overall performance over the GRA-7350T alone. Never having used an adjustable loading coil, I've not experimented to see if what I'm suggesting is even possible. Really appreciate stumbling across your channel. Keep up the great work ! AI4ME
Dave, you are making good suggestions. A longer antenna, like the BD7IBI, on the GRA-7350T would improve performance 20 meters and down. You do then sacrifice some of the portability as you have a longer collapsible antenna to carry. The great this is, we have all kinds of options.
I'm not sure if the Gabil can handle that extra weight, but I sure am gonna give it a try.
@@HOAHamRadio looking forward to your forthcoming video on it ! :)
Very well done video. Have you tried the GRA-7350T on higher frequencies such as 17m or 10m?
I haven't yet. 20 and 40 mostly, and I played with 80 and made some contacts. 80 I consider just a bonus; I would never buy this if my main operating was on 80 as it is just too much compromised that low. Gotta try 10 & 15 and see what it does.
@@HOAHamRadio Thanks. And again, well done. You're an excellent teacher/demonstrator
@@msgaltman3075 I was at Hamcation today and someone came up to me bragging about their using the Gabil 7350 antenna on Winter Field Day. Said all of this friends were asking and admiring. Then he fired up and made contacts on 10 and 12 meters....so, I'm guessing good on the higher bands. Like I said, I've made a few contacts on 80, but I wouldn't buy this antenna if 80 meters was were I hung out.
Thank you. Good video. Indeed it’s helpful. What software are you using for cat control? And that’s on a Yeasu 991a if I’ve seen that right from your previous videos. I have the 991a and having a heck of a time getting wsjxt to work with a MacBook usb. Realizing windows and ham seem to work better as I’ve been able to use ft8 on a 10yr old netbook that barely boot. Anyway I digress I was curious about the software you’re showing. It might be in a video you e made. If so if you. An point me there is be glad to watch. Thanks -73 de KK4GMR
Ken, I'm using a RSPdx receive SDR connected to my PC, running SDRuno on my PC, Windows 10. Its a fairly involved setup. I haven't done any videos yet, but plan to some day. And, its the FT991A, also connected to the same PC.
@@HOAHamRadio thank you Sir!
Besides a capacitor cap saving 15% power loss, someone needs to figure out how to stop the massive power loss from the coil.
Thanks for watching JB.
Did you test SWR on 2M?
I did while on the tripod with HF radial set up. My memory says it was just under 3:1. I expect with a mag mount on metal it would be better; didn't have a mag mount at the time.
@@HOAHamRadio thank you!
Great video! I was wondering where you got that s0239 adapter at for connecting the whip to the ground spike or tripod?
Here is an Amazon link: amzn.to/3Pw7d8i They are also on eBay, sometimes less expensive -- you are looking for a Comet AD-35M
