 Single C-Band (Wimax) Orthogonal Feedhorn with mini LNB

DESCRIPTION

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

If your antenna is located near a wireless tower transmitting power in the 3.5-3.7 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 LNB utilizes a 2nd order band-pass filter between 3.7-4.2 GHz and rejects all noise sources below 3.7 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: Use a feed rotator to tune both polarizations if necessary.

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