BPF-88-108MHz 100W FM Band Pass Filter with N-Female Connector, Anti-Interference, Improves FM Reception Sensitivity

Product Description:
This FM Band Pass Filter is specifically designed for the 88–108 MHz FM broadcast band. It effectively suppresses out-of-band interference caused by increasingly complex electromagnetic environments, significantly reducing background noise and improving receiver sensitivity and signal-to-noise ratio.

By attenuating strong medium-wave and shortwave interference signals outside the FM band, this filter allows weak FM broadcast signals to be received more clearly and stably.

Key Features:
* Precisely designed for the 88–108 MHz FM broadcast band
* Effectively suppresses out-of-band interference and spurious signals
* Significantly improves FM reception sensitivity and signal clarity
* Low insertion loss ensures minimal signal attenuation
* Suitable for both receiving and transmitting applications
* Rugged metal enclosure for stable RF performance

Applications:
* Ideal for environments close to medium-wave (MW) broadcast stations
* Suitable for areas affected by strong MW or shortwave transmitter interference
* Recommended when shortwave transmitters interfere with FM radio reception
* Improves overall signal-to-noise ratio in high-interference RF environments

Usage Instructions:
* Connect the filter in series between the antenna and the FM receiver.
* For long-distance or weak FM signal reception, an LNA (Low Noise Amplifier) can be installed between the filter and the receiver to further enhance performance.

Important Notes:
* This filter does not suppress interference that falls within the 88–108 MHz passband.
* Its function is limited to reducing out-of-band interference only.
