If the required level ratios are observed, a maximum number of three amplifiers can be operated in a cascade.

Amplifier voltage supply

Kathrein amplifiers are equipped with an innovative powering concept. The amplifiers can be powered in two ways:

1.Through remote feeding via the coaxial cable of the “H low” connection on a terminal multi-switch

2.Through connection of the optional NCF 18 power supply unit to the “DC” socket (does not include powering of the feed system!)

Potential equalisation

For potential equalisation use an earthing wire with a cross section of at least 4 mm. The unit is to be earthed using the earthing screw provided on the unit. Each unit in the reception system must be earthed.
