6m 50-51MHz 1500W Band Pass for Magic Band
Magic band 6m 50-51MHz 1500W Band Pass Filter uses high Q coils and capacitors with Q of more than 4000. Low loss of the filter is achieved with careful design and adjustment.
Intended to be used with linear amplifiers 8877, GS35, GS31, 2xGI7B, and with other tubes up to 1.5 kW output.
Although this filter is intended to be used as a transmitting filter, its design also allows it to be used as a receiving filter. It can be used before Wide Band LNA with PGA-103+ to protect sensitive devices from out-of-band signals.
A low insertion loss filter should be placed before any LNA to protect the receiver from HF transmitters in DX expeditions or in multi-multi environments. This BPF will suppress any harmonic on 100 MHz, 150 MHz, and more, and it will protect it from HF stations.

Measured characteristics of 6m 50-51MHz 1500W Band Pass Filter
50-51 MHz 0.11 dB, Input RL -30 dB
Maximum power input at SWR:
1:1 = 1500W, 1:1.5 = 1200W, 1:2 = 1000W, 1:3 = 800W
These excellent results were achieved by the careful selection of components and the design of the filter. Band Pass filter will eliminate any harmonic emission from your linear amplifier.
