Procom BPF 70/4-HX/h N(f) 440 - 470 MHz
The BPF 70/4-HX is a 4 helical resonator band-pass filter with aperture coupling between the resonators.
This filter can be used as a preselector to protect a receiver from interference from transmitters outside the band-pass limits.
When installed in the output of a transmitter, the BPF 70/4-HX reduces spurious signals.
