POLYTRON‘s new LNB range offers you the highest professional quality reception stability. High-quality components increase reliability and service life.
POLYTRON LNBs will win you over, since they have the highest levels of cross-polar discrimination, high noise suppression, a low linear noise figure across the entire bandwidth and stable linear curve behaviour to cope with the most demanding digital signals.
The Quattro LNB has four polarisation outputs and is used for setting up multi-switch systems and headends.
The Circular-Dual LNB has two polarisation outputs that have left-hand and right-hand polarisation.
