BPF 2/4-…

The BPF 2/4-… 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 2/4-C (C = cable) 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 2/4 reduces spurious signals.
The BPF 2/4-… is adjustable over the range 144 – 175 MHz.
Very compact due to use of helical resonators.
Careful choice of materials ensures reliable performance over a wide temperature range.
Extruded aluminium sections, steel racks and coaxial cables and connectors with teflon insulation ensure good mechanical strength.
The filter is coated with black vinyl to prevent corrosion.
