The original G5RV antenna was designed to work on 20 meters with some gain. Hams soon realized that it could work well on other bands using an antenna matching unit (tuner). I've used them for many years with excellent results. I had my reasons for using this particular antenna while working as a lighthouse keeper for many years.
Thanks for the info!
Curious to know what the special reasons were for the G5RV? Something to do with lighthouse? Also, wondering what it was like operating from a lighthouse. Sounds very interesting.
It now seems to be popular to criticize the G5RV. What most folks don't understand is that it was never designed to be a multi-band antenna without a tuner. What it is is an antenna that can be very easily tuned to multiple bands with good results. It is actually a better antenna in the current times with many rigs having very capable tuners built in. Some rigs though, have very limited tuning range, the Icom 7300 (a great radio otherwise), being an example of that. Anything over 3:1 swr and you can forget it. As you said though, with a radio with wide range tuning like the G90, or with an external tuner, the antenna works great.
ur excerpts from the various QSO's u had was perfect, especially to highlight how well that antenna works!🇺🇸😃
Thank you!
The fishing pole support in the center's a great idea!
Tim is a talented antenna builder.
My first Ham antenna was a G5RV back in '77, and made my first Novice contact (on 80m) with it. Good Video!
Thank you! 73, Walt
Funny story about G5RV antenna
I pastored a church , started a ham radio club with the youth, WG4UM (Working Georgia 4 United Methodist)
The hall way in the church was 103 feet long
We put discreet marks on the floor as a template to build the antenna and one summer the youth would come during the day and build G5RV antennas and sell on eBay.
They learned a lot about electronics and building stuff. All got their ham radio license
Most of all we had fun
That's awesome! What a blessing. Thanks for sharing!
I built my own G5RV years ago and it was great. I ran it through a Ten Tec tunner and loved it. I don't have the tall trees on my place that I used to so a reduced antenna might be the way to go. I studied the G5RV design quite a bit and one thing I found out was that the 10 meter portion of the antenna is the verticle section of ladder line. Thanks again, 73s KE4VBB
Thanks for commenting and sharing. All the best and 73, Walt
Do you imply that if I disconnect the two “arms” the ladder line will radiate in 10m?
@@NamasenITN I would think it should.
@@1boortzfan The wind just disconnected one of the arms of my G5RV. My radio's tuner refuses (of course) to work in any band but 10m. However the procedure of automated tuning fails. I conclude you might be right and that my tuner may still find difficult to work with high swr.
@@NamasenITN You might try taking off the other leg just so it's balanced.
The G5RV is a Fun Antenna for sure. 💯🔔🔔🔔👍
It sure is!
I have heard mostly great things about that antenna.
I’ve enjoyed it, pretty good antenna
Walt:
I had the same sized 1/2-scale G5RV up between 2006 and 2022 in a small back yard here. The only way it would fit in my yard was tp erect it as a sloper. The top was up 30 feet (9.1 meters) with the far end up 7 feet (2.1 meters). The 51 foot length is great on 10 and 6 meters, 3/2-waves on 10 and 5/2-waves on 6. I ran CW & SSB from 2006 until 2011, then mixed digital along with SSB and CW until 2022, normally under 40 watts but occasionally up to 75 watts. Between a spell on disability from a job-related accident followed by retiring 5 years ago, I spent plenty of time on the air, managing to finish DXCC/Mixed, WAS/JT-65, WAS/Mixed and I am 1 band from 5BWAS! Gotta say, for a compromise antenna, it works, and works very well!
BTW: I also have 239 grids on 6 meters during the same time frame, the first 120 grids with the G5RV/2 and the rest on a Par OA-50 loop, an antenna you might want to try some day!

Good stuff! 5BWAS is 80/40/20/15/10. How well does it work on 80? TIA 73 VE3GKT
Thanks for sharing!
Hi VE3GKT: The half-scale G5RV was too far out of the range for the tuner in the Yaesu FT-450, but could be matched with an external tuner.because of the high SWR being tuned out, the losses in the tuner basically reduced the signal to zilch. I made a few local contacts on 80 meters, but a 29' random wire did a better job.
IMHO, thd half-size G5RV is not suitable for 80 meters.

Hey Walt, Hope they are treating you well over in Poland. I recently got one of Tim’s EFHW antennas. Works like a champ. Didn’t realize until I finally got one of his antennas that he lives about 15 miles south of me. AC9DJ
Hey Jim! Doing well here.
Thanks Walt.....Looks like a good one.
Yes I really enjoyed this one.
cool, a mini G5RV, BUT u really should check out the modified version of the classic G5RV, the "ZS6BKW"! Have had mine for many yrs, worked the world & for most bands, I only need my rig's internal AT, nothing external! & love hearing ur CW, yes, great job! 73 de WA4ELW in TN 🇺🇸 dit dit 😃
Hi Walt,
They were some nice contacts with Tim's mini G5RV. Still hoping to make a contact while you still are over there. Stay safe. 73 WJ3U
Thanks Don! Gotta couple weeks and hope to catch you on the air. 73
...but should add, as u prbly already know, the ZS6BKW is a bit shorter than the original, just 94' long
👍Thanks for video. I put up a "temporary" half-G5RV about 10 years ago. It's still up and used pretty much daily! I did notice an improvement on receive when I installed a 1:1 voltage balun at the bottom of the window line. I sometimes wonder why doublet type antennas (including G5RV and it's variants) are not more popular. For example, balanced feeder is way more effecient than expensive co-ax. Doublets debunk myths like effecient antennas need to be half-wave resonant or need to have 50 Ohms feedpoint impedance.
Thanks for watching! Yes I agree.
Hello, very good video I am considering the g5rv full size and I am wondering if I can just tighten each end only of each side without the center support? would it be enough? or too risky in your experience? Thanks G7ned getting back on after 40 years!
I think you can do that if you can get the ends up high enough. Good luck and thanks for watching!
Back in 1989 on 21 mHz I worked Lois G5RV himself. Both of us using a G5RV and 100 watts, 5/7 both ways. I have his QSL with nice letter on the wall of my shack.73 de Mike VK3KTO.
That is so awesome, thanks for sharing! 73, Walt
Walt, I'm making my first HF rig a G90. I'm really impressed with your experiences. I really like this report on the N9SAB antenna. I'd have about a 50' coax run to its input. I'd run it through the basement to the outside then underground to its termination as a permanent installation with the G90. What coax would you recommend? Do you cut your coax runs to size?
Hi Dennis, thanks for watching my channel. To be honest I just use coax I get on Amazon, no special brand. I use RG8x and no I don’t cut to size I just find a way to lay the excess out of the way.
What size (guage) wire is tĥat? Great video as usual.
Thanks! 20 AWG
WALT, I LEFT YOU A QUESTION TWO WEEKS AGO ON YOUR VIDEO, PIER PORTABLE-PORTABLE HF W/VERT ANTENNA. IF YOU CAN GIVE ME SOME INFORMAYION I WOULD APPRECIATE. THANK YOU, I WILL CHECK BACK ON THCE SAME VIDEO TO SEE IF YOU HAVE ANY INFORMATION.
Sorry I missed it, been extremely busy and working long days.
Hi Walt, as a newby to Ham Radio, I have a question about this kind of antenna. Would this work if the two horizontal arms were at 90 degrees to each other rather than 180 ? 73, Pete 2E0IKX
Hi Pete, that’s actually a great question. I think it would work well as a L shape if the 90 degree bend was with the long piece horizontal and the shorter side down towards the ground. As far as a 90 with both horizontal I think it would work OK but might direct more of the signal out from the corner. You’ve got me thinking now, I might have to experiment. 73, Walt K4OGO
@@COASTALWAVESWIRES I will be watching with great interest! But actually I do that already!
Hi Walt - I have used a full size G5RV antenna at several locations over the years and had good luck with them. I’m a little older now and not so nimble, so my last instillation was a 40M EFHW. SWR is amazingly good on the non-warc bands, and it seems to radiate fairly well on 40 and 20, but not on the higher bands. Trying to hunt POTA running 10 watts, is all but impossible on 15 or 10. It’s possible that my issue is my location or installation. Do you have experience with the 40m EFHW, and if so, how would you compare the two antennas with respect to the signal out. I have a tuner so SWR is not an issue.
Thanks - I enjoy your videos.
John, WA4RXO
Hi, I've built quite a few 40M EFHW antennas and to be honest I'd say they are pretty similar with signal out. I actually prefer the EFHW because it is easier to deploy being end fed. All the best and 73, Walt
Hey Walt, interested in the connection at the bottom of the ladder line. Is it one of those red and black 259 jobbies with a double female into coax ??
No it’s just a BNC connector at the bottom of the ladder line
Hi Walt, I bought this antenna I’m bout use it for portable, does it work ok as an inverted V ?
Yes it works as an inverted V but I would try to elevate it as high as possible
Were you using an amp for these contacts?
No just 20 watts
Thanks for the quick response. Hey I live in the Hampton Road area (Hampton). We should probably do a show together. I have a youtube channel also. www.youtube.com/@BlackHamRadioUniversity/videos
are you working for Jeppesen ? :D
No I’m not
@@COASTALWAVESWIRES take care! SP7EZG
Some of this is just brilliant. You just do great work that helps all of us out. If there were awards for this, you would have won a long time ago. Safe travels. de Lc
Thank you so much!
interesting kg6mn
What type of pole support are you using?
It’s a 7 meter fishing pole I got on Amazon
basically a 51' radiating doublet plus something that helps the tuning....so that is 25.5' per side & for every balanced antenna there is a single sided unbalanced equivalent fed against earth so 25.-ish' of vertical metal plus something to help tuning plus an ATU.... hey we have just described the Rybakov antenna (just a different tuning helper but that doesn't impact the radiation) & lots of people like them. Just like we have unbalanced rubber ducks on VHF but run a balanced equivalent on HF & you call it a slinky antenna. Funny how basically the same concept gets so many names. You want to get really silly?... cellular inverted F antennas family history... balanced dipole antenna begats balanced slot antenna, begats notch antenna, begats balanced skeleton notch antenna which gets cut in half to become unbalanced & fed against a groundplane to become the Inverted F antenna..... I've always wondered how these would do on HF (more importantly to avoid groundplane efficiency problems, stopping one step early at the balanced skeleton notch could be interesting for HF... who is going to get their name on that?).
