The MDA20U amplifier is based on a new concept of convergent technology.The characteristics of
the IC selected provide a noise figure that is lower than any other product currently on the market
and an output figure that surpasses most distribution amplifiers hence the name Masthead
Distribution Amplifier (MDA).
The MDA20U is a multipurpose amplifier that is ideal for our digital and analogue environment.
Whether the unit is used as a Masthead or Distribution Amplifier the low noise figure, capacity for
multiple channels with low distortion and a high output provides a solution to all installations and
is proven especially effective in digital problem reception areas.

The head of the amplifier may be mounted outside on the pole under the antenna or in the roof. The amplifier
requires F type connectors.
The power supply unit is placed at a television outlet, or at a remote location, a low voltage then runs up the
cable to power the head remotely, via the output. There are no controls inside the diecast housing, however
there is an LED that when on, indicates power is present.
