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

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 LNBF?
An LNBF is an LNB with an integrated feedhorn
What is a Monoblock LNB?
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.
