I got my tower back up and this afternoon as I rotated the 34XA I noticed
the sigs cutting out. SWR was 3.5 to 1 rather than 1.2 to 1
on both 20 and 10 (little change in 15). I feed the antennas thru a remote
coax switch so I checked that out first and the 12 and 40/17
antennas worked fine. SO it comes down to the 34XA. I had problems with
the dual drive straps(between the driven elements) and traced the problem
back to the connections. I worked hard to tighten the contacts and clean
them so
its gotta be the center connection that keeps them apart with a spacer
insulator. The SWR and sigs jump when I tap the break release on the rotor.
The beam settles down after a while. The problem occurs when moving the
antenna
but is worst between NW and N. I have replacements but probably will have to
wait until
next spring. I put on a new balun and made sure that was secure, too.
Does anyone else have any other suggestions?
