- The BPF 70/4-HX-C 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.
- The BPF 70/4-HX-C (C = cable RG316) can be installed directly into the PRO-AR4G-N, PRO-AR8G-N and PRO-AR16G-N receiver multicouplers as a preselector.
- When installed in the output of a transmitter, the BPF 70/4-HX-C reduces spurious signals.
- The BPF 70/4-HX-C is adjustable over the range 380 - 470 MHz.
- Very compact due to use of helical resonators.
- The careful choice of materials, ensures the filter will function reliably over a wide temperature range.
- Extruded aluminium sections, steel racks and coax cables for PCB mount with teflon insulation ensure good mechanical strength.
- The filter is coated with black vinyl to prevent corrosion.
