 Dual C-Band (5G) Orthogonal Feedhorn with mini LNBs


Dual C-Band orthogonal feed featuring anti-interference 5G bandpass filter. If your antenna is located near a 5G wireless tower transmitting power in the 3.5-3.8 GHz microwave band, it will overwhelm the small amount of power coming from the communications satellite resulting in intermodulation signal interference.

Symptoms of 5G interference include: complete signal loss on some or all satellites or partial signal degradation on a few satellite transponders and normal performance on the rest. To combat such intereference, this LNBF utilizes a 2nd order band-pass filter between 3.8-4.2 GHz and rejects all noise sources below 3.8 GHz and above 4.2 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 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 for a consumer satellite receiver setup by using a 13-18V voltage switch (sold separately below).

Note: This product works well for rejecting light 5G interference. Examples of such interference includes picture pixelation and audio screeching on some transponders over the satellite arc.

Note: If you are experiencing heavy signal interference on most or all transponders across the satellite arc, then you must also purchase a mechanical waveguide post filter (sold separately below) that has a much sharper filter cutoff response and extremely high stop band rejection. This latter solution is highly recommended for TV and Radio stations.
