2m and 70cm Double 2x200W BandPass Filter 144-148MHz 430-450MHz

Special Double 2x200W BandPass Filter 144-148MHz 430-450MHz designed to suppress not just HF, 6m, 4m, and FM stations but also in between frequencies like 170MHz, 210MHz, harmonics like 288MHz plus harmonics like 720MHz or 880MHz.

Low insertion loss and 2 x 200W power on both bands 2m and 70cm characterize this product. Double bandpass filters for transmit and receive will prevent receiver overload from any out-of-band stations.

Especially good to put it in line with DualBand 2m-70cm single connector antennas.
