The Lectrosonics UFM230L Inline Antenna Filter and Amplifier Module is a small, yet rugged device that installs between wireless receivers and antennas that are installed over long cable runs. The UFM230L both amplifies antenna signal and filters to prevent intermodulation (IM) and overload. Two ceramic resonators provide 230MHz bandwidth filtering, followed by 12dB of gain and a +41dBM output. User adjustable jumper placement provides +5dB, +8dB and +12dB of gain.
