Bandreject filters RF5-1V are recommended to use in radio stations and repeaters receiving section if nearby powerful transmitter, operating at known neighboring frequency, is present. These are signals of paging transmitters or repeater native transmitters, usually. Bandreject filter enables to effectively eliminate interference at significantly lower frequency separation, unlike bandpass filter. Model RF5-2V is assembled from two single filters RF5-1V, connected by cables in series and fastened mechanically by metal brackets.
