HORWIN DF-VM6-SH – is a compact VHF 6 rectangular cavity base station duplex filter. Bandpass/reject duplexer is useful for repeaters, duplex base stations, and other applications when combining of both receive and transmit frequencies into a single antenna is needed. Each filter is individually made and tuned, so receive and transmit frequencies should be specified when ordering.
