In my quest to get rid of desense with
the Quantar, someone mentioned that having

but the 150-160 MHz version, and there is
a bit of a mismatch.
Has anyone ever had any desense that they
could attribute

Have you checked the repeater for desense without the antenna installed? As in
most commercial repeaters they are usually designed for larger spacing than 600
kHz. Check it without the antenna and all open ports terminated with a 50 ohm
termination. Then add the antenna and look at the
