Installing and connecting the power unit
The power unit provides 12VDC power for the aerial’s amplier, choose a location within 1.5m of
the TV/VCR or Freeview™ receiver location, so that the ylead supplied will reach the relevant
aerial socket and within approx. 80cms of a 3 pin 13 Amp mains socket.
PLEASE NOTE: the following safety precautions before installation and use
•A ventilation gap of at least 25mm should be left around the front and all sides of the unit
•Do not leave the power unit resting on a carpet
•Do not leave the power unit where it may be smothered with curtains or other fabrics, etc.,
•The unit is not waterproof and should not be exposed to dripping or splashing water.
•Objects containing liquids should not be placed on or near the unit.
•To prevent the risk of re do not expose unit or wiring to excessive heat or naked ames.
Fix the power unit ➊ to a wall, skirting board or similar hard surface in the location you
have chosen using grab adhesive or silicon sealant.
Wire the remaining F connector supplied ➌to the end of the aerial downlead (see Fig. 1 & 2)
and connect to the ‘IN’ socket of the power unit. Use the ylead ➋supplied to connect the TV
socket of the power unit to the coax aerial input of your receiving equipment.‘F’ connectors
should be tightened gently with a spanner (11mm).
Technical data
Testing and adjustment
Plug the power unit’s supply lead into a mains socket and switch on.Your ‘Megaboost’ aerial
system should now be working. Check reception on all analogue and digital channels.
Final
adjustment to the aerial alignment can now be made.
Most digital receivers have a signal strength and quality display screen, this can be used (with the
aid of a helper) to align the aerial for best reception. On completion, fully tighten the nuts on the
aerial mast clamp and ensure that all xings are secure.
Reception hints and troubleshooting
See also the recommendations in “Select Mounting Position” on page 1.
If you receive no channels rst check all connections.
If you can view some but not all the available channels, try moving the aerial to a different
part of the building. Height is usually the single greatest factor affecting the strength of signal
received by an aerial. Some areas are covered by two or more transmitters. Experiment to nd
which gives you best reception. Digital reception can be affected by interference from spark-
ing switches and thermostats etc.To eliminate this mount the aerial outdoors and always use
CAI approved cable, or a cable of equivalent quality. If a wall outlet is used it should be fully
screened and “non” isolated.
