It sounds like a connection is loose somewhere along the line. You probably
need to "wiggle" some things to see if you can cause a reproduction of the
problem.

Subject: [TowerTalk] Flaky dipole
Hi folks. Sending this to multiple groups to gain expertise.
My primary dipole is acting strange. Its 135 feet of wire up 40 feet. Fed
with ladderline. As I am transmitting I noticevthe swr going from low to
high suddenly for a few seconds and then back. Initially I thought it was
my auto tuner showing damage, butvI put an MFJ manual tuner in place and I
can clearly see it happening on the meter. I dont think it is wind moving
the wire, as it was calm when it was happening. The feed goes from the
rig, through the antenna switch to the tuner, then out the window via a
bulkhead connector and to the 4:1 balun via a 2 foot coax, and then to the
ladderline.
Any ideas on where to look for issues, and or testing methods?
Thanks
