Twin 4-feed LNB for 9°E, 13°E, 19.2°E and 23.5°E for 80cm dish


Item: 5094


This 4 Feed twin-output LNBF is a monoblock LNBF for Ku-band satellite reception from orbital positions 9˚E, 13˚E, 19.2˚E and 23.5˚E. It is intended to be installed with commercially available 80cm satellite dish antennas with f/D ratio of 0.6. 


The LNB receives satellite signals in a frequency range of 10.7 to 12.75GHz divided into Low Band (10.70 to 11.70GHz) and High Band (11.70 to 12.75GHz) and in both horizontal and vertical polarizations. The LNB provides two independently switchable IF outputs (Twin model). These ports carry also power supply and control signals and are F-type.


DiSEqC1.0 commands allow switching each of the outputs to a particular band and orbital position. “ODU A” corresponds to 9°E, “ODU B” to 13°E, “ODU C” to 19.2°E “ODU D” to 23.5°E. As long as no DiSEqC command has been received, the default feed is 9°E. The LNB comprises four feeds, one for each orbital position. The feeds allow mounting into the feed clamp of the satellite dish. The feeds are marked with “9˚E”, “13˚E”, “19.2˚E” and “23.5˚E” respectively.

Frequently Asked Questions

What is a feedhorn?

The feedhorn is the part of a satellite dish system which gathers the reflected signal from the dish and focuses it towards the LNB.

What is an LNB?

An LNB - Low Noise Block (also called an LNC- Low Noise Converter), is used for communications (broadcast) satellite reception. The LNB is usually affixed either in or on the satellite dish.

What is an LNBF?

An LNBF is an LNB with an integrated feedhorn

What is a Monoblock LNB?

This design consists of two independent LNBs in a single case. The two LNBs can be automatically addressed with any DiSEqC 1.0 or higher receiver. In some cases they can also be addressed with ToneBurst / MiniDiSEqC. However, they are only available for satellites with a fixed 3 degree, 4.3 degree, 6 degree …spacing. In Europe, for example, there are monoblock single, twin and quad LNBs for the Ku band, which have a pre-defined spacing of 6 degrees (for Astra 1 / Hotbird , for example).

Why can I receive only one satellite with my Monoblock?

Monoblock LNBs are designed for a specific dish size, 80cm for example. If your dish is too small (70cm for example) or too wide (90cm for example) it is not possible to receive both satellites together. Please choose the dish size for which the monoblock LNB has been designed.
