6 meter 200 W Extreme Low Loss Transmitting and Receiving Band Pass Filter

Transmitting 200 W 50 – 52 MHz band-pass filter for chasing DX-es sunk into the noise.

Low Insertion loss filter is excellent to be placed before any LNA to protect the receiver from HF transmitters in DX expeditions or in multi-multi environment. This BPF will suppress any harmonic on 100 MHz, 150 MHz and more.

As its attenuation is only 0.11 dB, and the possible maximum output power is 200 W, this bandpass filter is ideal for both reception and transmission.
