- Here you can see how a very simple loop antenna designed for the AM broadcast band can help boost those weak stations on the band, they may help to hear that station you have a difficult time pulling in and are just fun to experiment with also.

I live 85 miles from the Canadian border and have this Tecsun loop aerial. At 1 am eastern time I took my tiny Sangean am fm portable and started tuning around using the Tecsun loop. For a year or so I have been hearing a Spanish speaking station on 530 khz on my Icom and Yaesu rigs and the 75 meter coaxial fed windom so, just to find out if it would be there with the tiny Sangean and the Tecsun loop I tuned the radio to 530khz and peaked the loop and it was there. No US or Canadian stations are there so as I rotated it the north south orientation nailed it. The signal was the best I had ever heard it! It was Cuba and they were playing some great music. The signal was so good I listened to the music for about 90 minutes or so with hardly any QSB at all. On or about that frequency at the east west orientation there was another station there. The loop had nulled out Cuba almost completely so now I want to eventually nail that other station which is due east somewhere towards Europe. You guys should try 530 khz and listen for Cuba and then for that station due east. Probably Europe but until I can get a World Radio TV Handbook I will have to keep guessing!
Hi! Pointing to Europe, and close to 530kHz? It's 540kHz, isn't it? If so, you are receiving the station MR1 Radio Kossuth of the Hungarian National Radio network. This is our last remaining AM broadcast frequency, transmitting with 2MW. The transmitter has been completely replaced recently, the new transimitter is in service since 11.27.2017. It replaced a 40 years old 2MW Soviet tube transmitter, the new one is a solid-state Canadian Nautel with five 400kW units. They also kept the old tube transmitter, as a spare for the new one, it can be re-utilized in minutes, if necessary.
Thanks Larry, found a "Terk Advantage" loop off of Ebay and gave it a try on the AM band with the Satellite 800.
They do work and a S/N ratio goes way up like your demonstration shows. I like your the vintage Zenith radio! 73s
I recently bought one of these Tecsun Loop antennas and it performs far above my expectations. I use it plugged into the Hi Z input on an SDRplay RSP2 through SDRuno software on a laptop. The feature I really appreciate is the filtering of interference outside of the tuned frequency range. It is really fun for pulling in distant or low-power signals by turning the knob and physically moving the loop.
I found them on eBay cheaper than amazon. Like 10-15$
I'm going to have to look into this. My Grundig S350 definitely use it. Thanks for posting this video.
I have recently purchased the AN100 model which is electrically identical and it is surprisingly effective for its size. I have built 2ft square loop antenna which works very well but is too large and unwieldy to use inside the house. My Degen DE1103 radio is capable of receiving Transatlantic BC band DX at my home in southern UK, using only its ferrite antenna around sunrise when conditions are right, but the AN100 can boost things a little more. Received WTNI on 1640 from Mississippi on 2 mornings a few days ago.
Good job on the video, Larry. Thanks.
Sold! Just bought one after trying to vaguely listen to Monday night football. Thank you young man!
I've made my own Loop antenna and works so well!! 👌🏼👌🏼
Thank you for making this video. I have been thinking about purchasing one and now I will.
Great presentation. Thank you.
Love the video Larry. Keep up the good work! Did a RX loop review like this only outdoors, had great results as well. Great video as always Larry
I like the loom antenna best. Ive got one like it made from a 16 inch x 6 cheese form.
Great explanation! Thanks, Larry
I have one of these. So simple and and elegant. My 50's era Transceanic has what they called a "Wavemagnet" in the cover. Same idea.
Thanks good review and demo.
I think I'll be getting one soon.
This loop thing really helps my signal at night cuz it's a crappy signal at night so thanks dude.
Great to hear! They do work well most of the time.
I am just writing this to let you know how good your presentation style is. You don't try to be a comedian (whilst failing miserably) like some other presenters, your are not boring like so many (surprisingly) popular others, you don't feel that you have to use all the tricks your video software can do and your delivery is fluid without loads of "ums" and "ahhs". Plus you actually seem to know what you are talking about. This video was am absolute pleasure to watch so naturally, I have subscribed to this channel.
Mni tnx es 73 de Guy G4DWV/4X1LT
Very nice,I been lestening to short wave radio,at night.
Great video .have one on its way from China can't wait for it to arrive.
Thanks for the demo. I'll have to check it out. I still use a Palomar Engineers active loop purchased in the late 1980s, but it would be nice to have a second loop for other radios around the house. 73.
I remember those Palomar loops, always wanted one of those for the VLF band..
thank for the reply radioguy..im also very impressed how it picks signals simply without any external power input..it impressed thomas henry morray as well who went on to make history building controversial energy devices in the 1930s ..please link it up to a led and see if it can light up any simple led with the right capacitance resonance with relation to the coil winding
thank you, I built the 'cross' type antenna years ago. ony bigger, works fine
I love em. Not ugly at all. Very nice and vintage looking. Like all the old black and white photos you see people using cool loops just like this for longwave.
I haven’t used my loop in a few years. It does not look like yours but it works great. I hook it up to my Onkyo stereo receiver. I never used it on my communications receiver because of the noise. I’m so glad I sold that thing. Well anyway, I got some great DX in the month of November right after the time change. These were daytime stations in the south in the central time zone an hour before they go off the air. I still have my log book. Another great thing about my loop is by tuning, turning or both, I can nullify stations. One time I nullified WIP in Philadelphia and got WIOD in Miami! I’m going to hook my antenna tonight just to see what’s out there. It will be a clear, cold night; perfect conditions for DXing the AM band. During the summer it’s a waste of time. Keep up the great job with your videos.

Thanks, yes, this is about the best time of year for AM band DX. I have been tuning around and hearing stations I have not heard in a long time. That is what I like about the loops, you can zero in on the station and get rid of some of the noise many times also..
Beautiful Zenith receiver btw. I've been checking this antenna over the internet for a while. The reason I haven't bought it yet is very bad quality programming of Brazilian AM stations. I recently moved to in a region that is good for DXing foreign stations,. Thanks for your demo.
+jtownshend Sounds great and happy DX'ing!
Good work dude
When I was a teenager, I would take my 6 transistor radio outside and stand beneath the nearby high tension lines. I could pick up east coast stations from northern California. The same principal. Different scale.
I have 2 of these loops and they really work great! You can take 2 of these loops and set them in a straight line with each other close to a am radio and they will work better also, you just have to experiment with the distance between the first and second loop for best reception.
great to know, I will have to play around with that also...
CARL BOLEY
Interesting. Thanks for the info.🙂📻👍‼️
I bought one and it’s great
I have the "Grundig" version of that antenna. They work great! RW
Great helpful video thanks
Another great video RHG. Very useful as well. Looking out for something inexpensive and gradually move up to a Wellbrook version. Costing reasons. Want to improve my AM listening and this will help temporarily until the Wellbrook comes along. Thanks again RHG.
Thank you very much, it is all fun! I still do a lot of AM listening late nights. 73
Great stuff.
Thank you very much sir from Bhuj gujrat India
LIKED YOUR VIDEO....VERY GOOD.
i picked up a tecsun loop mw antenna works 100% i paid around 20 english pounds very good passive loop for the price.
Pete Smith I’ve just ordered one
I've got terk am advantage loop, I presume this performs much the same ?
There's also a guy here in Australia who makes them, PK's Loop Antenna & they also work really well :-)
very expensive though and a person can make their own very easily.
There's no way that I'd spend over $100 for a loop Antenna to pick up am radio
Hi RadioHamGuy, which AM loop antenna is better: Terk Indoor AM Antenna ADVANTAGE or Kaito AN-200 Tunable Passive AM Antenna.
A comparison video from you would be great.
What a sweet man.
Again, very dependent on the radio used. I've found that very small radios benefit the most. The small ferrite bar needs a boost. I own two, and the improvement is quite impressive. Great video!
Excelente explicação! Parabéns
Nice video, thanks - what model is the Philco pocket Rx?
Yes they do come with multiple brand names. Mine says Grundig but it's exactly the same, even the plug-in cable.
I think I will get one of these to experiment with and compare to my hula hoop broadcast loop I made.
That would be interesting, I think the hula will probably do better since it is larger but if you try that , let me know how it does, would be curious.
I have a Select A Tenna, works great. It nulls out interference too.
Increased my signal and volume as well as number of stations recived
I don't do a lot of MW listening but I'm still a little tempted to pick one up
A very long wire also works very well .
I've been looking on ebay for an am antenna for my scanner which goes down to 100khz but I've never got a signal due to the tiny rubber duck antenna, this I think is worth a try. Thanks.
I use the AN-200 Loop Antenna, too
Great stuff man, thanks.
But please try to use a sketch on paper to show how it works, so people do not think it is magic ;D
For instance you show a Coil (L) and tuning cap (C) with symbols and #s and some simple formulas for frequency and waves,
Keep it up & regards
“Viagra at huge discounts” lol
Nice. I may have to build something like that. But I think first I need to have another go at a magnetic loop antenna for HF.
Yes, I like playing around with those HF loops also, they can really work well for portable use!
Thank you…
Good video i just built an AM receiver with MK484-1 but i have no ferrite coil i hear just tchchchchchchchchch so that will helps?
Hey Larry, I have built several of these and they work great. Radio Shack have some like yours and I think they wanted 90 bucks or close to that. Hmm , and now they're gone.
Thanks
Carl
:::: had :::::
skycarl Hi Carl, yes, I am going to miss the local radio shack, was nice to get parts once in a while. Some good deals now though I guess. They sure are not what they used to be though but times change I guess and I think ordering online sure changed it for them for the worse. Times sure change I guess.
RadioHamGuy here in Australia we have Jaycar. they seem much better value than radioshack. i got a 8kg bag full of resistors, relays, capacitors, large ceramic resistors, contactors, transistors, even a few vfd displays. the whole bag for 20 bucks. if you were to buy everything individually it would cost over 100 bucks.
Little hello from France
Thanks for all of your videos and your cool way of doing them.
I bought this antenna and am disappointed that nothing is happening in LW.
Do you know if there is the same type of antenna that would also allow me to improve long waves? Thank you for your help .
My radio is XH Data D808 and it works in MW
I am not aware of any for LW that are commercially made, I know there are plans on the internet and calculators I have see to make your own. Yes, this antenna will not tune down as far as LW. The only way might be to make your own from what I have seen out there.
interesting it really works, reckon we can use that booster antennae to build a crystal radio set?
fidel catsro Yes, I did just that with my home built loop, just added a diode and high impedance earpiece and it picks up my local AM station just fine since the tower is only about a mile away, I have impressed a lot of people demonstrating that to them, they just can't believe they are hearing a radio station with just that and no battery.
I have an 80ft external long wire, do have any thoughts on how these small passive loop antennas compare?
Many times they work better since you can null out noise sources and point them in the direction of the station also.
Jaycar (Australia) also sells one. It’s a few dollars cheaper, but there’s no information about it that I have seen.
I just bought the Tecsun antenna and it didn't really do anything for my reception. What I am wondering is if I could make one that is better .... meaning if you increase the number of loops does it work better? What kind of wire did you use? How many turns. Where did you get the capacitor and what range is it. Personally, I like you home made version of this better than the Tecsun, it looks cool.
Cool. I would have thought it was a hoax device if not for your video. Thanks for the tip.
Thanks Todd, yup, they do really work, and just a basic tuned antenna circuit. Hope you are doing well. 73
Hoping this may work with a stereo console. The attena is weak on it.
Please tell me prise this radio antenna 🙏
Great video! I have the Tecsun loop antenna, but don't have the right cable to plug it into the back of my Icom 756 (SO-239). Can you recommend a cable (where do I find the proper one), so I can connect this loop to my Icom 756? I think it would be a 3.5mm stereo connector to a PL-259. Thanks!
Thanks, and yes that is the cable you would need. If you can't find one with the PL-259 you might have to use one with the SO-239 and then use aanother adapter or coax jumper to make the connection.
@@RadioHamGuy Thanks! That's what I was thinking after scanning the internet for such a cable (3.5mm stereo to PL-259). I couldn't find one, and i'm really not good at soldering, etc.
very cool.
I just picked up a Motorola Am/Vhf Transistor radio. less than 5 bucks on ebay. one of those antennas would be perfect for that.
73,kb3aum
Might be worth a try Dave, they do wonders on portable radios that have the built in ferrite loop stick antennas. 73 and nice to hear from you!
When you have the option to directly connect the wire to terminals on the radio, do you find that works better than just placing the loop near the antenna?
I find that it really depends on the radio.
Tecsun and Kaito are one in the same. Tecsun is the name Kaito is sold in the US under.
Fellow ham, shud u mention how u cannot inductively connect a loop antenna to a radio unless the radio already has its own (internal) loop (ferrule)?
Hi. Very cool. Do you know if this will boost an old tube radio that has an internal loop already? I see you tested a tube radio in this clip.
I have tried it on a few radios I have like you are talking about and found that it does still help in that situation also.
This looks really useful. Would it work with the NOAA weather radios too? I have a KA500.
This would not work for NOAA weather broadcasts on the VHF band, this loop is only designed for the AM radio band but for that it works very well.
I have one of these, works on most all radios. The only radio it doesn’t work on is my Tecsun Pl-390 - Don’t know why.
Well worth the price.
I got mine directly off of the California based ( for U.S. customers)
Kaito.US website.
I love the old Zenith ‼️
🙂👍📻📻📻📻🙂👍
वाह 😊👌❤
Hi,
I'm a bit confused regarding the orientation of the antenna towards the station.
If the station is directly south of me, should the 'open' ends of the loop facing S-N or should they be facing E-W?
Thank you!
The open ends should face E-W. The loop picks the signal up from the wire ends if that makes sense. So if you were to put a yardstick along side of the loop touching both ends you would be pointing the the right direction, however, it is the same off of both ends, bi-directional. Hope that helps? I know, it used to be confusing for me so let me know if this helps.
@@RadioHamGuy That helps alot. I understand now. Thanks again! 🙂
Try this on SPARC HD RADIOS. and also Tivdio and Tecsun LW radios.
I got mine direct from Kaito.US
About $20.oo Well worth it.
Works with almost all radios. (Doesn’t work with my Tecsun Pl-390, But does with my Pl-600).
I'm seeing these on eBay and it seems like most of them just come with a 3.5mm to 3.5mm cable. I notice yours has the bare wires at the end, which is what I need. Is there a way to choose?
I have not looked in a while but there was no choice in what it came with when I got mine.
I’ve just ordered one on eBay. I know they only work on medium wave am but does anything exist for long or shortwave apart from a long wire?
Supposedly you should be able to get one of these to work on lw by adding capacitance
Almost magic :) 73s
HI, Can you use 2 at a time.? Thanks
What is AM radio DXing?
The old ham operators called ithat sympatedic oscillation
Get ready for 20th March (eclipse) should be good for MW I hope.
Great video . I've seen one made by grundig.awhile back . great video BTW Ramsey makes a ferrite loop type active antenna. But its like 90 bucks if you have it do a demo. If you lost a little weight in your face you'd look like Harvey Keitel. Do you dance lol
Thanks, and oh, I can't dance very well, but sometimes not bad, lol.
I have the Radio Shack version. It didn't seem to work, I will try it again since it has been shelf candy for a long time. Got it on a RS junk table manager red tag deal, very cheap.
I hear that some closing RS's are having great junk table deals, gotta check them out for parts dtc.
yea, that is too bad to hear about Radio Shack. Some good deals however.
Can it be turned into a crystal radio
"Now you can finally get Viagra at huge discounts!"
Should I buy an antenna or viagra?
Esteban F. I need to get a girlfriend first
👍👍👍
If the loop antenna larger, would it pull in more stations?
A larger size loop does generally work better, it would probably require less turns of wire also.
Thanks!
I have one of thease I'd recommend
Analog receivers works better for AM reception.
I can tune a radio stations from Cuba here in NC on my 1970 receiver with manual dial.
I find just the opposite.
Build your own good, send the other one back, even better.
Will it work on shortwave?
No it will not, this loop is only resonant across the AM broadcast band.
could i make one with no dial?
Connor Baker You would need the tuning capacitor to change the frequency but as for the dial itself, it would not have to be on there, it is just a way to tune the capacitor and have a relative indication. By dial I am talking the knob itself.
Does it also work for shortwave?
The ones you see here will only work for the AM broadcast band. There are others that are larger that can work for shortwave however.
You know a sw Extreme distance with the same connector single ring Jack plug
Does this loop help at all on fm or jus am?
+Bill Hoffman This loop only works on the AM radio broadcast band.
duckduckgo.com/?q=FM+loop+antenna&iax=images&ia=images
does this work for SW too?
This one only works for the AM band
Hi Larry, can you use that loop to improve SW recep? Thanks, 73
Joe KC3BXZ
This loop will only cover the AM broadcast band but there are other types of loops for SW that will work there.
Can be used for SW?
These will only work across the AM broadcast band, they can be built for SW bands however but different dimensions than this.
I can get Kaliningrad on my medium wave radio from England
