An antenna with good standing wave ratio can still have loose or noisy hardware causing desense - If possible be sure the clamps that hold the folded dipoles are good and tight, and check the harness connections to the dipoles. Also, is there other equipment at or near the site that might cause some mixer product?

I hope someone can shed some light on this?
If I have my repeater at home it works with 30 Watts out now problem.
When I bring it back to the repeater site I have to lower it to 5-10
Watts because I get RF feedback to the radio. It just sounds like the
squelch is always open.
Motorola Mitrek modified for duplex
Coax is the same at both locations, LMR400
Antenna is the only thing that is different, using a fiberglass Alpha
Delta full wave vertical at home and at the repeater site it's a
commercial 4x Folded Dipole.
SWR on the antenna at home is 1.5 to 1
SWR on the antenna at the repeater site is flat
Thanks
