INSTALLATION MANUAL
• A masthead amplifier is designed
to amplify low signal levels for both
analogue and digital applications.
• The amplifier gain should be selected
to suit each individual environment.
• Mount with polypropylene securing
strap on to mast or mount to a wall
with cable connectors at the bottom.
• Best Mounting location for masthead
unit is on mast 30 cm to 100 cm
below antenna.
• Ensure weatherproof strips remain
in place.

TECHNICAL ADVICE
1. Check there is no earth braid touching the centre
conductor on the coaxial cable.
2. sI there more than one outlet? Check the
splitter box, the power supply must be connected
to the coaxial outlet that feeds the AC/DC leg of
the splitter box to pass power to the head unit.
(Check if LED is on).
3. sI there now too much signal causing an
overload effect to the VCR? Try turning down
the gain controls on the masthead unit, or select a
smaller dB rating amplifier.
4. fI there is a white line moving through the
picture?
Try a PSK06 14 V DC power supply.

simply removing the shorting link and placing it on
the specified terminals. The FM trap must be in the out
position to view television channel 3.

(Pager Filter maybe removed if you need
to amplify 5A, simply remove 2 coils as
indicated on the PCB above the VHF input.)
