 Linear C-Band Dual Output (5G) LNBF


Introducing our C-Band, Dual Output, consumer grade LNBF with anti-interference 5G filter. 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 signal interference.

Symptoms of 5G 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 interference, this LNBF utilizes a 2nd order band-pass filter between 3.8-4.2 GHz and rejects all noise sources below 3.8 GHz.

High gain, low noise and excellent stability makes this LNBF the best choice for mitigating interference. This LNBF lets you connect two or more receivers to get all C-Band satellite transmissions with your 180cm, 240cm, 300cm, 350cm or 400cm prime focus dish.

Note: This is a consumer grade 5G LNBF. It 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, this product may fix some transponders but likely will not fix them all. In this case, you will require a commercial grade orthomode feed with a mechanical waveguide filter that has a sharp low-pass cutoff response. This solution is recommended for TV and Radio stations. Please see our commercial feed products.
