Radio Frequency Interference (RFI) Automatic Filtering

Filter Out Select BAS Channel Interference Automatically

Troll’s TMF-350 is an automatic RFI relay switch designed to monitor the control signal of a receiver and determine whether to bypass or in-circuit filter individual channels. Used widely by cellular phone companies to automate the process of filtering select channels, the TMF-350 passively monitors channel and band conditions based on the status of the receiver to determine whether the filter should be in or out of the signal path.
