After IC-718 radio and Diamond's SX-600 power meter test, the input power to this bandpass filter is 125w and the output is 110w-115w (slightly different depending on the frequency band)

Note:

Special Occasion:

This band-pass filter is suitable for use in short-wave communication where the radio station is very close to the medium-wave radio station or is subject to strong medium-wave interference, and can also be used in the occasion where the short-wave radio station interferes with cable TV users during transmission.

General occasions:

When the short-wave 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.
