Satellite channel router
  • active Active

Relaying satellite signals from the rooftop dish to multiple receivers around the home, Digital Video Recorders (DVR) or throughout an apartment block is an expensive proposition for system installers. The SaTCR-1 satellite channel router addresses this problem by combining up to eight input signals onto a single cable. These signals are then decoded by a corresponding number of tuners, potentially distributed across many set-top boxes.

The SaTCR-1 device is intended for use in LNBs or switchers in satellite receivers. The device shifts the frequency of any input signal to a fixed intermediate frequency. The output signal is bandpass filtered generating a narrow band output.

By combining several SaTCR-1 devices, a corresponding number of sub-bands may be generated and multiplexed together.

This composite band can be made of different independent channels issued from different LNB inputs and polarizations, and can be carried on a single coaxial cable.
