HD Radio Isolator FM7380

Isolator

The FM7380-6HF FM HD Broadcast Isolator

fm7380The FM7380-6HF HD Isolator is designed for digital HD broadcast applications that require extra isolation.The FM7380-6HF is inserted between the HD FM Transmitter and its coax system (load) to reduce intermodulation products associated with return analog signals being received by the digital antenna element(s), coupled down the digital coax system and mixed in the output circuit of the HD FM Transmitter. The system design uses a combination of convection and fan assisted cooling. The 115 VAC fan is thermally sensed and activated as required. The isolator is self contained and mounted on a standard EIA 19" rack mount panel for ease of installation. It is suggested that one RU of space be provided above and below the unit for air flow and cooling.
