FM Filter



The Channel Master FM Filter improves over the air (antenna) signals by filtering out FM signal interference.

The Channel Master FM Filter is designed to clear your OTA TV signal path from the common interference created by overpowering FM radio signals. FM signals have been known to cause issues with TV antenna reception for many years now and FM interference was even more pronounced during the analog days. The Channel Master FM Filter is a high-quality filter encased in a metal all-weather housing that is designed to be installed either indoors or outdoors. The filter blocks FM frequencies starting at 88MHZ and ending at 108MHZ with precision start and stop signal roll-off which prevents the filter from causing issues to adjacent TV channels.

Common situations in which FM interference to TV reception occurs are, your antenna is located within two miles of an FM transmitter or your antenna is located further than 2 miles but there is a presence of strong FM signals at your location. FM radio towers are a common cause of intermittent television signal disruption because transmitting FM signals can be received at a much stronger signal level than OTA TV signals. In some cases, this can be problematic. These disruptions can be short in duration and result in intermittent weak signals, pixilation, channel loss, and can be especially disruptive when using an amplifier with your TV antenna.
