Features Include:
•High gain and low noise built-in amplier
•Suitable for Digital TV in strong signal areas

Installation Instructions
1. Plug the integrated aerial coax lead (Fig. 1)
from the aerial into the antenna (RF) input
on your set-top box, or TV.
2. Connect a SCART lead from the SCART
output on your set-top box to your TV.
Alternatively, connect an aerial coax lead
(not supplied) from the RF output
on your set-top box to the aerial input
on your TV (if in doubt check the
instructions for your set-top box).
3. Switch on the variable gain control
and set to maximum amplication
(turn control clockwise as far as it will go).
4. Rotate and tilt the UHF loop antenna to
obtain the best reception (see Fig. 2 & Fig. 3).
5. Adjust gain control to obtain best picture signal.

The RF IN coaxial socket on the back of the aerial
(See Fig. 1) allows an alternative video source, such
as an outdoor aerial, cable TV, a video game, or
satellite receiver to be connected to your TV via the
aerial. This saves you having to keep connecting and
disconnecting the coaxial cable running to your TV
and also saves wear and tear on the TV coaxial socket.
To select the signal from the aerial, switch on the
gain control. The red power LED on the front of the
aerial will light up, while this LED is lit the signal sent
to your TV will be from the indoor aerial. To switch to
an alternative video source connected via the RF IN
coaxial socket simply switch o the gain control
(power LED is not lit).

Troubleshooting
Digital TV
Problems with DTT (Digital Terrestrial Television)
Unlike analogue terrestrial television, it is not
possible to view DTT channel under weak signal
strength conditions. Therefore, typically you will
either receive DTT channels with a clear picture
and sound or you will not receive any channels at
all. Sometimes, an insucient digital signal can
cause occasional blocking, freezing or complete
loss of picture. Try the following to improve the
picture:
1. Tilt and rotate aerial.
2. Adjust Gain control.
3. Position aerial at greater or lesser distance
from TV until optimum signal is received.
4. Check the mains connection and fuse
Blocking, freezing or complete loss of picture
can also occur when a digital signal is too strong.
Adjust Gain control to obtain best picture result.
Analogue TV
Poor Signal Strength (analogue)
If the picture suers from snowy grainy signal try
the following to improve the picture:
1. Tilt and rotate aerial to obtain the best picture.
2. Adjust Gain control to obtain the best picture.
3. Position aerial at greater or lesser distance
from TV until optimum signal is received.
4. Check that the adaptor is properly connected
to and aerial.
