Hi Barry - If I had another hand I would give you three thumbs up for that. Since I don't I'll just give you two. I agree that too many people get too worked up over too little things. Just try to us
I agree with Barry's observations as well. I have worked some decent DX with less than perfect matches. Worked my first C5 on 80 meters with a 3.5:1 SWR. My only question about the balun was to minim
John, As you realise, adding a choke to the G5RV is not primarily about improving the match or saving dB - it's about stopping the ladderline, and more importantly the coax, from becoming part of the

I've never given much thought to SWR when it comes to operating. OTOH I having operated multi op close to stations using open wire line I learned to dislike it with a passion. Yes, I use a line tuner

It would be interesting to review the source article by Varney, entitled "An Effective Multiband Aerial of Simple Construction," RSGB Bulletin, July, 1958, pp. 19-20. By 1958, the 15m band should ha

There are two stations within 3 miles of me using G5RVs. dimentioned for 40. On 40 meters I easily work stations with a sloping, center fed, half wave dipole they can not hear and I apparently have a
I don't know where this "ham myth" comes from that the original G5RV was just a 20m antenna! Varney's original article published in the RSGB Bulletin, July 1958, is entitled "An Effective Multiband A
This is exactly right -- except that common mode current is equally possible, and equally undesirable on parallel wire line as compared to coax, BECAUSE of the noise coupling issue, AND to prevent th
My G5RV's are 'get on the air' antennas with 100w and an ATU, but a dipole per band or set of fan dipoles work better in my experience and have a useful and predictable pattern but take more work. TA
Jim, You'll see I said "it's about stopping the ladderline, and more importantly the coax, from becoming part of the radiating structure." The reason I suggest that CM on the coax is more problematic
