Gang, Ray I got a 59 foot run of RG8X from the wireman 10 years ago and added the nice 1 to 1 balun. The first problem I had was the PL259 on the RG8X would not match up with the S)239 in the Balun.
Dave, Try putting the reflector on a small milk crate or other non conductive box, and aim the beam towards the sky. Guy with some ropes to keep it standing more or less upright, pointed up. A 40m be
It is possible that the old coax PL-259 threads are out of round. They can get smashed or possibly the threads are bad. If other PL-259's fit the balun you should be fine. I never bother checking SWR
I don't find that the "point the beam skyward" method works that well on 40M beams for doing the initial SWR test. The typical 40M beam is a loaded element and on a boom that is usually 20 - 24 ft lo

Dave, Checking a 40 meter beam that close to the ground will drive the best frequency way down the band even below 7.000. You need to get the 40 meter beam up at least 50' to get any reasonable resul
If that isn't possible at least point it straight up and get it as far off the ground as you can. Resonance will still shift up some. Jim Rhodes K0XU _______________________________________________ _
I have never tried tilting the a beam up. It seems like a lot of trouble, especially with a long boom and I would not be confident that it is still tuned properly. It is quite easy to pull a beam up
Last year I prepared a Cushcraft 40-2CD and a HyGain 402BA for Field Day. Each would not show good sweep results and would not radiate well while the boom pointed up and even with the reflector end r
Quite a few years back I had a 40' Rohn tower with a system 36 by Wilson on it. The tower was setup to tilt over on a hand winch with a ginpole. I could tilt the tower over very near the ground with
