Yes. Many repeater receivers are simply not well enough shielded to
keep the TX from leaking into the RX box. Even some commercial
repeaters will suffer desense if 100% shielded feedline is not used. I
have seen serious desense occur when a dual-band (2m/440) antenna is
used on a repeater, due to the uneven gain versus frequency response of
many such antennas. Invariably, the desense went away when a good
broadband antenna was used.
