 Single C-Band (5G) Orthogonal Feedhorn with mini LNB


This is a single output orthogonal C-Band feed horn with anti-interference 5G filter used for the reception of either Vertical or Horizontal microwaves. It includes a mini (5G anti-interference) LNB which bolts to the end of the waveguide.

If your antenna is located near a 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 single transponder and normal performance on the rest. To combat such interference, this LNB 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.

It is designed to receive a single microwave polarization and conduct it to the mini LNB for down conversion.

Note: This feed horn setup is typically used by cable head-ends. If you only require a single polarization, use this feed horn to get the maximum possible C/N.

Note: More efficient than a dual orthogonal feed due to better impedance matching and less cross-polarization interference.

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 recommended for TV and Radio stations.

Note: Includes the feed horn and mini LNB for a complete single polarization solution.
