The DTV Frequency Shift Repeater (FSR) is designed to solve problems of weak mobile signal, which can expand more coverage than RF repeater and reduce investment for the areas where fiber optic cable is not available.

The repeater is working as a relay and frequency converter between the TV transmitter and receivers during the broadcasting of digital TV signal. It receives low-power TV signal from the TV transmitter via the Donor Antenna, then converts it to specified frequency, and retransmits it via the Coverage Antenna to the weak/blind coverage area. The FSR can avoid self-oscillation which will be easily caused by the RF repeater.

Application Diagram of DTV FSR

To expand signal coverage or fill signal blind area where digital TV signal is weak or unavailable.

The DTV FSR is mainly applicable to such case:

In comparison with RFR (RF repeater) and FOR (fiber optic repeater), the FSR has the following benefits and disadvantages:
