application:

Special Occasion:

A: This band-pass filter is suitable for the occasions where two or more shortwave antennas are erected at the same location and work at different frequencies at the same time. Such as the occasion of communication games.

B: Band-pass filter (BPF) with higher isolation is suitable for occasions where two or more shortwave radio stations share a pair of multi-band shortwave antennas and need to work at the same time.

General occasion: When the shortwave radio is working, in order to reduce the electromagnetic interference from the surrounding as much as possible, this band-pass filter can be connected, which will greatly improve the signal-to-noise ratio.
