Band Pass Filters “LowBandSystems” are very high quality multi-stage devices designed to specifically limit the RF band pass to a single Amateur band. They eliminate image and harmonic RF interference issues for dedicated mono-band operations in multi-radio contesting environments.
Required for use with transmit multiplexers, these passive filters add the isolation needed to allow multiple transceivers to be operated on different bands simultaneously on the same antenna.
Band Pass Filters achieve 60 to 90 dB of out-of-band suppression that virtually eliminates out of band noise and interfering signals.
Insertion loss is negligible; typically 0.3-0.5 dB in band!
The filter set consists of 6 band pass filters with a maximum power of 200 watts ICAS for the following frequencies:
1.8MHZ / 3.5MHZ / 7MHZ / 14MHZ / 21MHZ / 28MHZ
