 Single C-Band (5G) Orthogonal Feedhorn with waveguide post filter and mini LNB


This is a single output orthogonal C-Band feed horn with dual anti-interference 5G filters used for the reception of either Vertical or Horizontal microwaves. It includes a mechanical waveguide post filter and mini electronic LNB filter which bolt together to make the most powerful 5G anti-interference feed system available anywhere on the market today!

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 feed uses a mechanical waveguide with posts to reject out of band interference and an LNB with a 2nd order band-pass electronic filter for additional stop band rejection. This combination is guaranteed to reject all interference 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: Commercial grade 5G anti-interference c-band feed system guaranteed to perform or your money back!

Note: If you are experiencing heavy 5G interference that blacks out almost all satellite transponders, then this is the only feed horn solution that will recover your c-band satellite reception.

Note: This feed horn system was field tested 400-ft from a 5G wireless transmitter in a major metropolitan area on a 12-ft satellite dish. It recovered all affected satellite transponders. In the unlikely event that you do not recover all transponders, simply add a 2nd waveguide filter (sold separately) for additional interference suppression.

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 solution is highly recommended for TV and Radio stations but can also be used by backyard satellite enthusiasts who are unhappy with the performance of consumer grade 5G filter solutions.
