2 Way Plug-In Aerial Amplier
Introduction
This SLx plug-in aerial amplifier is designed to improve picture and sound quality by amplifying
weak UHF and VHF signals.
4G Ready - built-in lter removes interference and channel loss caused by 4G mobile phone signals.
These instructions cover the most common installation options. However, if you need further
advice, please contact our Customer Careline (see overleaf).
Please Note: If used to boost signals from the RF2 output on a satellite receiver you will need a TV
with an analogue tuner to view the satellite signal.
Boosting the signal to your TV / Freeview ™ Box / PVR
Standard installation for weak signal areas
1. Connect the UHF aerial downlead (typically via an aerial
wall socket) to the INPUT socket of the SLx amplifier.
2. Connect an aerial flylead from the OUTPUT socket of the SLx
amplifier to the aerial input (usually marked “ANT IN”) on the
back of your TV Freeview™ receiver or PVR (digital recorder).

Tuning your TV
Once you have made your connections switch on your equipment.
Tune the TV to terrestrial television channels and tune any other additional piece of equipment
connected to begin viewing. Consult your equipment instruction manuals for tuning details.
Adjusting the gain level
The plug-in amplifier has an adjustable gain control. The gain level can be adjusted to optimise
signal strength. This model can boost the signal by up to 20dB.
Please note: The maximum gain setting will not necessarily give the best picture and sound.
Adjust the gain gradually until you find the setting which gives the best results.
1. Turn anticlockwise to increase the gain level
2. Turn clockwise to decrease the gain level
Problems with Digital TV
It is not possible to view digital TV channels under weak signal strength conditions.
Therefore, typically you will either receive channels with a clear picture and sound or not at all.
Sometimes, a weak digital signal can cause occasional blocking, freezing or complete loss of picture.
Some old roof aerials are not be suitable for digital TV. Ensure that you have fitted a suitable wide-
band, high gain aerial to help improve signal quality to a suitable level for clear DTT reception.
Blocking, freezing or complete loss of picture can also occur when a digital signal is too strong.
Turn the gain level down to minimum and gradually increase the gain to find the best gain level for
a good picture.

Intermittent Connections
Make sure that all coaxial cables are free from twists, kinks and tight bends as this may damage the
inner core of the cable and result in poor picture/sound quality. If you have fitted the coaxial
connector to the cable yourself please ensure that all connectors have been fitted to the cable
tightly (both inner and outer), preferably soldered.
