Band pass-reject filter PRF5-1V is tuned to pass specific frequency and to reject another specific frequency simultaneously. Filter PRF5-1V with band pass-reject feature is essential if nearby interference is present. Install this filter in receiver antenna section and tune rejection in to interfering signal, and you will appreciably improve receiving conditions attenuating interference by 35 dB. Filter PRF5-2V has higher characteristics at corresponding loss. Unlike common bandreject filters, this filter has one very useful feature; it can be adjusted to passing with perfect VSWR without any difficulties, which can be only achieved by painstaking selection of tuning cable in bandreject filters.
