METHOD 2:
Video Cassette Recorder (VCR) Playback
1. Connect your UHF aerial downlead to the
RF input socket of the VCR.
2. Connect the RF output lead of the VCR
(usually connected direct to the TV) to your
aerial ampli er IN UHF socket. Both TV and VCR
playback signals will now be available on each
outlet of the ampli er.

METHOD 3:
Satellite Receiver Signal Distribution
If you wish to distribute signals from a satellite receiver:
1. Connect your UHF aerial downlead into the satellite receivers UHF aerial input.
2. Connect the output lead from a satellite receiver to your ampli er UHF input.
Signals from the receiver can now be watched on all TV sets connected.
3. Alternatively connect the satellite receiver output into your VCR.
4. Connect your VCR output as per METHOD 1. UHF TV, VCR playback and satellite
receiver signals will now be available to all TV sets connected.
5. Connect the outputs to all TV sets.
N.B. It may be necessary to retune the output channel of your VCR when used with a satellite
receiver. Consult your VCR user guide for information.
Use of Gain Control
Gain Control is used to adjust ampli cation for optimum signal strength (0~10db).

If you are still experiencing reception
problems after the installation of your
Analogue Terrestrial TV
Snowy Picture
A faint, grainy or snowy picture is generally caused
by a weak signal. Normally the TV transmitter
will be a long way away. A possible improvement
could be made by reducing the aerial downlead
losses, installing a high gain aerial and by adding
of cases, a snowy picture can also be caused by a
TV signal that is too strong.
‘Herringbone’ Pattern
‘Herringboning’ is generally caused by too strong
a TV signal or by a local high power transmitter
such as CB, amateur or taxi radio. Your TV sound
may be affected as well as the picture. Using an
attenuator will reduce the gain of an aerial signal
and improve the overall picture.
Digital Terrestrial Television
Unlike analogue TV signals that can still be viewed
under weak signal strength conditions, with digital
terrestrial signals blocking/freezing and/or loss
of digital picture and sound can be caused by
Similarly blocking and even a completely blank
screen with no sound can result if the input signal
to the set top box is too high. The digital cliff
refers to the rapid change from the picture
and sound being perfect, to disappearing
altogether.
When interconnecting equipment and to
get the best carrier to noise, place the digital
in the signal path followed by any video or
satellite receiver.
Fitting a high gain wideband roof aerial may
also improve the reception and signal quality.
Digital signals are generally immune to
perfectly receivable under conditions where an
analogue signal would suffer ghosting.

Digital Satellite Television
With digital reception, a weak signal or
incorrectly aligned dish will cause the picture
and sound to block or disappear. Check both
the alignment of the dish and skew angle of
the LNB.
Intermittent Connections
Make sure all RF cable to connector joints
are tight (both inner and outer) including all
