 Dual C-Band (Wimax) Orthogonal Feedhorn with mini LNBs

DESCRIPTION

Dual C-Band orthogonal feed featuring anti-interference Wimax filter. If your antenna is located near a wireless tower transmitting power in the 3.5-3.7 GHz microwave band, it will overwhelm the small amount of power coming from the communications satellite resulting in signal interference.

Symptoms of Wimax interference include: complete signal degradation on some satellites or partial signal degradation on a single polarization and normal performance on the other polarization. To combat such intereference, this LNBF utilizes a 2nd order band-pass filter between 3.7-4.2 GHz and rejects all noise sources below 3.7 GHz.

This dual C-Band orthogonal feed can be used for simultaneous reception of vertical and horizontal polarities.

It separates the vertical and horizontal polarities and conducts them to their own waveguides. It includes two mini Gardiner LNBs which bolt to the end of the waveguides.

This feed setup is typically used by cable head-ends to allow switching of both polarities to multiple decoders/receivers. You can also use it on a single receiver setup by using a DiseqC 2x1 switch and separating your channels listings by polarity.
