Here it is about overload protection for antenna inputs in the satellite technology. This protection is used directly before the antenna distributor respectively multi-switch and protects thus the connected inputs reliably against overload. The protection device is equipped with five F-couplings, which can handle both analogue and digital satellite signals and terrestrial antenna signals. The signals can optionally be connected to any F-coupling through the universal protection circuit. The side-mounted plastic holder allow direct wall assembly. To connect the distributor to the multi-switch the F-adapters are No. 61 51 21 available. Adapter is needed for every channel connection. With the connection cableOrder-no.61 51 22 the distributor can be connected to a multi-switch with divergent grid measure easily. Adapter is needed for every channel connection.
