Invacom Prime Focus LNB

 

Invacom Prime Focus LNB s for Prime Focus Satellite Dishes in Spain

An LNB is a device mounted on the dish, designed collect and amplify the satellite signals and convert them from a high frequency to a lower frequency. LNBs can be controlled to receive signals with different polarisation (horizontal and vertical). The signals can then be carried down the cable cable to a satellite receiver.

An LNB can be either single (one output), Twin (two outputs), Quad (four outputs), Quatro (four outputs), or Octo (eight outputs).

A Twin LNB would be required when more than one receiver (or a PVR like Sky+) is used allowing the viewing of different channels on two independent satellite receivers.

A Quad LNB would be required when more than three receivers.

A Quatro LNB would be required when requiring to install a multiswitch system that can provide feeds for many receivers, as in the case of a community system installation.

These Invacom Prime Focus LNBs require a separate feedhorn / wave guide to be attached to the LNB.

The Invacom Prime Focus LNB Single SNF-031 is proven to have poorer performance than the Invacom Prime Focus LNB Twin TWF-031 LNB and the Invacom Prime Focus LNB Quad LNB QDF-031, which is why these Invacom Single SNF-031 should no longer be installed.
