Bandreject filters RF8-UL have found themselves in radio stations and repeaters receiving section operating closely to powerful transmitter, operating at known neighboring frequency. Bandreject filter enables to effectively eliminate interference at significantly lower frequency separation, unlike bandpass filter.
Presence of 3/4-wave cavity in bandreject filter will save your transmitters from persistent signals of paging transmitters or telemetry systems, located closely to your antennas.
Careful selection of cable junction in RF8-2UL and RF8-3UL filters provides maximum convergence of pass and reject frequency preserving low loss.
