1.25m 219-225MHz High Power Band Pass Filter 2000W

Low-loss 1.25m 219-225MHz High Power Band Pass Filter 2000W with high attenuation out of band signals. Excellent for transmitting and receiving. Use this filter after any linear amplifier up to 2000W. Filter will suppress any signals from HF 1.8 – 28 MHz stations, 50-54 MHz, 2 meters, and 70 cm – 432 MHz (430 – 450 MHz) stations. The filter will reduce TVI problems or your problem with neighbors with strong RFI from HF, 6-meter, 2-meter, or 70-cm transmitters.
