My A4S is acting wierd and I cannot figure it out.

20 meters its got great SWR. 15 is so so but tunable with a tuner
and stays relatively flat.

However 10 meters, the SWR stinks and I can try to tune it with a tuner
but then it goes out again. And I can swing the beam and hear the
Noise pick up and go down with the turning of the beam and when it stops
it wiggles a bit and the SWR changes. The tube and trap connections all
see secure.

Do I have a bad trap or ?????

Coax connectors or water intrusion are often a problem.
