The PerfoBox transmitĀ band pass filters from Low Band Systems are high quality devicesĀ thatĀ eliminates image and harmonic RF interference in multi-radio setups. They are designed to be used inĀ SO2R or Multi-OperatorĀ contestĀ effortsĀ or byĀ DXpeditions with more than one station on the air simultaneously.
PerfoBox 200 wattsĀ filters are available for each of the nine HF Amateur Bands and offers excellent rejection of 60-90 dB of out-of-band suppression. Each filterĀ isĀ easily identifiable by the laser cut frequency on top of the device which is not only practical, but also makes your station look great.
Band pass filters are also required for use with transmit multiplexers. These passive filters add the isolation needed to allow multiple transceivers to operate on different bands simultaneously usingĀ the same antenna.
