Note: With the continuous complexity and harshness of the modern electromagnetic environment, the aviation frequency band radio is greatly interfered. When it is turned on, it will be very noisy back noise, which makes the useful signal flooded. Therefore, China Antenna Network has launched it, which is suitable for current frequency modulation. The band-pass filter used for stereo radio reception can reduce clutter interference. After installation, it will greatly reduce out-of-band interference.

suitable occasion:

This band-pass filter is suitable for applications that are close to medium-wave radio stations or are subject to strong medium-wave interference. It can also be used where short-wave radio stations interfere with FM radio receiving users during transmission. In order to minimize the electromagnetic interference from the surroundings, this band-pass filter can be connected, which will greatly improve the signal-to-noise ratio.

usage:

Connect this band-pass filter in series between the antenna and the receiver. If you want to receive remote FM stereo radio stations, you can install an LNA (low noise antenna amplifier) ​​between the filter and the receiver, which is also available in our shop. Those in need can contact the owner.

Special attention: If the interference comes from the passband of 118-136MHz, this filter has no effect.
