■ Their circuit is integrated in a Zamak box, which ensures correct operation of
■ Allow return path operation and have slope control for the direct way.
■ The DWBA 415 model is a double extension amplifier, valid for a two-cable
system with two independent satellite TV circuits and a common one for
terrestrial TV, in addition to the return path.
■ The amplifier has been optimised by specific circuits which protect it against
telecommunications services on adjacent frequency bands.
■ Integrates a switch mode power supply to reduce the inside temperature and
help extend the life of the equipment.
