Overview

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.

Fm filter

Now have better picture and sound, picking up weaker stations easier.

Interference from the ridge

My review is very similar to the other reviews. I live in close proximity to the ridge where most of the local FM/TV/cellphone towers are located. Strong harmonics from those towers cause a lot of interference for antenna TV reception; interference that can kill the channel altogether, or can make the TV error message report that the channel is scrambled. The FM filter & 5G/LTE filter combo (connected in series between TV & rabbit-ear-antenna balun-coil-adapter) very nearly eliminates interference for nearby TV channels, & greatly improves reception of fringe area TV channels.

FM filter and LTE filter.

Installed FM filter along with LTE filter. They have greatly reduced interference of those signals, I have much less TV picture loss now. Good product.

Excellent FM reject filter, especially for its very reasonable cost.

There are several full power FM radio transmitters about 1 mile away from our UHF receive antenna. Recently, yet another FM transmitter came online which resulted in overloading our UHF pre-amplifier causing loss of reception for several channels. Installing a Channel Master FM filter at the Pre-amp input completely solved the overload nonsense. Prior to its installation I characterized this filter using a spectrum analyzer with tracking generator. Its response is -55 dB down across the FM broadcast band and virtually zero loss everywhere else. Note that you will lose a bit of channel 6 (82 - 88 MHz) and some of the aviation band (108-118 MHz) which, in our case were not important.

I highly recommend this filter for any receive antenna installation suffering from strong FM radio overload.
