The BPF 70/4 is a 4-resonator ¼ λ band-pass filter featuring inductive coupling between the resonators. It is designed to be used as a preselector, protecting a receiver from interference caused by transmitters outside the filter's band-pass limits. When installed at the output of a transmitter, it effectively reduces spurious signals. The BPF 70/4 is adjustable within the 380–470 MHz range and is built with materials selected for reliable operation across a wide temperature range. The filter features extruded aluminum sections, steel racks, and coax cables with Teflon insulation for enhanced mechanical strength. It is coated with black vinyl to prevent corrosion. The standard version offers a 4 MHz bandwidth, but other bandwidths, up to 10 MHz, can be requested when ordering.
