How To Fit A MASTHEAD AMPLIFIER & Power Supply Unit

This video shows you how to install a TV aerial masthead amplifier and power supply unit. With this type of amplifier the power supplied via the coaxial cable itself which usually plugs in by a TV. This makes it perfect for installing amplifiers in positions where there is otherwise no electrical power point to plug a traditional aerial amplifier in, like in lofts, outside or on the aerial mast itself.

In the video demonstration, A wolsey 4 way 0-10dB masthead amplifier and Wolsey 12V power supply unit have been installed onto a Optima log periodic wideband aerial.

Tools you will need:

1x Stanley Blade or Utility Knife
1x Side cutters

Parts you will need:

1x Masthead amplifier
1x 12V Power supply unit
F connectors
Insulating tape for securing cable to mast

Step by step guide:

Masthead amplifier

1) Cut the existing aerial cable where you intend to install the masthead amplifier.
2) Install F connectors on both ends of the cable.
3) Install a third F connector (If you're using a multiple output masthead amplifier) onto a new coaxial cable which will be fed into a new room, repeat this process for as many extra cables you will be installing.
4) Insert the aerial input cable into the input of the masthead amplifier.
5) Install all the remaining output cables and screw into position.
6) Tighten all F connectors with a 11mm spanner or pliers to maintain the integrity of the cable screen and to minimize RF leakage.
7) Secure the amplifier in position.

Power Supply Unit

8) Cut the aerial cable where you intend to install the power supply unit.
9) Install F connectors on both ends of the cable.
10) Screw the aerial side cable into the input of the power supply unit, often marked aerial or 12V.
11) Screw the TV side cable into the output of the power supply unit, often marked TV or output.
12) Plug power supply unit into mains point.
