Love the G5RV - my first main antenna. Someone gave me some lengths of cadmium copper and at first I fed with 75 ohm Suhner cable(someone donated). I continued to experiment and found quite a few archived articles on the subject, I then fed with open wire feeder all the way back to my tuner. I think I saw a photo of G5RV at his QTH with this feeder method. I need to search these things out of my clutter. Great vid. Thanks Mike

When I was going to high school in Canada, I got talking to our caretaker. As we chatted he told me about his career as a radio operator aboard commercial ships, rats electrocuted in the transmitter tank coil. Later he told me how he got interested in radio as a young lad, he would collect empty cigarette packets for the foil, splitting lead pencils to use the pencil lead to make resistors, I found all this riveting.

This is one of your best videos dude! My main issue with the doublet, G5RV or the ZS6BKW is the ladder line drop. I just haven't been able to implement that straight down pattern well. That said, those I know who use a doublet really get great results!

Many years ago I built a half size G5RV, including making my own open wire feeder. It was a pretty poor antenna, but I saw an article in QST about an antenna for the new 12m band. It was a 50 foot top and a 1/8 wavelength phasing stub to make a colinear. So I chopped the open wire feeder down and used it on 12m. Incredible antenna, especially as it was broadside to the USA and up at a fair height.

I love the story Peter. Wouldn't it be interesting to make a sequel about the ZS6BKW as it afaik is based on the G5RV.? I forgot to write down my actual lengths when I built my ZS6BKW, but at about 40 Ft in between two pine trees it is certainly a good all-round performer! 40m and 20m are matching almost 1:1 and for the other bands my external LDG tuner keeps the radio happy. Even on 15m where the antenna has a very high SWR. However, despite knowing that coax loss (100 Ft of LMR400) with such SWR is also quite high, and there might be just 25Watts being radiated, I did make several very interesting contacts on 15m! It has the same X shaped lobes as the G5RV, and thanks to those I make it into Europe, Pacific and Asia as well. I can't move the pine trees, but the pattern just worked out well. Despite Louis Varney's advise, I do use a 1:1 BalUn and Choke combination between the 450 Ohm ladderline and 50 Ohm coax. At the shack entry there's another 1:1 current choke inline to be sure there's no noise and common mode entering the shack that way. Both are rated 5KW so it will take some effort to warm those up.

Very interesting, Peter Thank You. I have a half G5RV and I think it's a brilliant antenna. It's only about 12 feet of ground level through a ladder line in a 90-degree 'L' shape around my fence supported on slate battens into 991A. The tuner in the 991A works perfectly into it and the furthest distance I have had is Nicaragua on 35 watts :) Happy Ham here. Thanks for the vid. 2E0WFL

My first antenna was a 100.' length of copperweld wire center fed with 450Ω open wire feedline, but eventually the little plastic pegs fell out of the feedline faster than I could glue them back in. Worked great with a HB antenna tuner with a HB 4:1 Balun at it's output. I changed to 75Ω coax after that. (RG-59) Ron W4BIN

@@watersstanton Hi Peter, I did try it out a few years ago and it does work on 160 but it does work best if the feeder is quite long and in the clear if possible as the top section acts more like capacitive loading as Marconi discovered with his famous T antennas. Keep up the good work Dave 😀

I prefer the doublet (random length wire dipole), and I do not use ladder line. I get low SWR on all bands with low loss running 100% coax, using an LDG RT-100 remote auto tuner at the feed point. For me it's the best, most versatile solution and a 100W remote tuner is still pretty light weight and low cost.

When Louis Varney said Balun I wonder if he meant a 4:1 Balun.I have noticed some older hams in my area think a Balun is 4:1 balanced to unbalanced. To use ladder line.

His concern was losses - I suspect any balun. Currently I am simply using a line isolator at the coax junction. This only has an effect on outer coax common mode currents and no effect on RF flow to antenna.

talking of antenna family trees... start with the balanced 51' per side g5rv... which begat the 25' per side half size 5rv... but for every balanced antenna there is the unbalanced half antenna which is basically 25' of wire going straight up, the feed ladder is basically just part of the match which is irrelevant to the radiation characteristics so keep the wire & swap the match slightly & what do you get but the Rybakov
