Blocks the broadcast FM band between 88 – 108 MHz with over 50dB of attenuation. Designed for RX use only.
Insertion loss is less than 0.5 dB between 0 – 1 GHz, and mostly less than 1.5 dB between 1 – 3 GHz. Uses SMA female connectors. Comes with a free SMA male to SMA male adapter.
A broadcast FM block filter can help if you have very strong broadcasts in your area that are overloading the SDR dongle. Also known as an “FM Trap”.
TV installers please read and pay very close attention to the following: This is probably not the right product for you. These filters are designed for software defined radio and radio scanner users. The filter uses SMA connectors. SMA connectors are very common in the professional RF world, but are NOT commonly used in home TV installations. TV installs normally use F-TYPE or PAL connectors. So this filter will not fit onto F-TYPE or PAL connectors which are common in the TV world without the use of an adapter, which is not supplied.
