Using PF5-V filters in antenna section of radio stations and repeaters you will raise selectivity of their receivers, lower influence of out-of-band interference, escape effect of UHF blanking by nearby radio transmitters and desensitization, and eliminate intemodulation interference, also.

Filters, installed in transmitters circuit, lower stray emission level and prevent intermodulation products occurrence. Recommended to use if equipment is installed in locations with high density of transmitting devices.

PF5-2V and PF5-3V filter represents two and three PF5-1V filters connected in series and combined by metal brackets. They have higher characteristics at corresponding loss.
