Using PF10-U series filters in antenna section of radio stations and repeaters you will raise their receivers' selectivity, lower influence of out-of-band interference, escape effect of UHF blanking by nearby radio transmitters and desensitization, and eliminate intemodulation interference, also.
PF10-U series filter has higher Q-factor, then 8-inch filters.
