Chris,
How are you measuring the SWR? Power meter or SWR analyzer?
The SWR analyzer is sensitive to strong RF signalss. You notice this at field
day when you see the SWR bounce all over the place because another station is
transmitting nearby. You don't notice it as much at home if it is caused by a
nearby AM transmitter because the power level (and incorrect SWR) is
continuous. My QTH is in the shadow of a 50 kW AM station and the SWR analyzer
is almost useless at lower frequencies and if the antenna is up high.
Remeasure with a SWR bridge. If still bad start checking cable and connector
connections.

I have just put up an A3WS with 30 meter add on kit. ?I used an old
wireman current balun that I believe is not working.
I need some advice on what balun to replace it with. ?
I want to order one ad soon as possible to put up in the even it ever
STOPS raining in Atlanta!
I have fought this antenna for 2 weeks climbing the tower in the rain,
in the dark, and in the dark rain. ?I am to my wits end. ?If I replace
the balun, and it still does not work, I plan on posting a video of me
towing this antenna off the top on my tower. ?
Last week I had the antenna back on the ground and disassembled every
trap on it, and found nothing out of the ordinary. ?When I put it back
up in the tower before cranking it back up, it sat at 24 feet and
functioned flawlessly. ?However, after turning my back for 5 minutes,
the SWR is all jacked out of whack again.
Somebody recommend anything, and I'll buy at this point...
Thanks and (I would) see you in the pile ups (if this damn thing would
work)!
