Note: with the increasingly complex and harsh modern electromagnetic environment, FM radio is subject to great interference. As soon as it is turned on, it is noisy back noise, which makes useful signals submerged. Therefore, China antenna network has launched a band-pass filter suitable for receiving FM stereo radio to reduce clutter interference, and the out of band interference will be greatly reduced after installation.
Suitable occasion:
When the radio station is used for medium wave interference, it can also be used for receiving medium wave interference. In order to minimize the electromagnetic interference from the surrounding, the band-pass filter can be connected, which will greatly improve the signal-to-noise ratio.
Usage:
If you want to receive remote FM stereo radio, you can install LNA (low noise antenna amplifier) between the filter and the receiver. Our store also provides it. If you need it, you can contact the owner.
Special note: if the interference comes from 88-108MHz passband, this filter will not work.
The spectrum field strength parameters without band-pass filter are as follows:
After the band-pass filter is connected:
