General Safety Precautions
TO PREVENT OVERHEATING: The recommended clearances and other precautions given in the
Installation section of these instructions must be observed to prevent overheating. In addition, the units should
not be fixed where they are likely to become smothered by curtains, or other fabrics, etc., or by thermal
insulation materials in a roof space or similar building void. The units should not be !eft resting on a carpet.
OTHER PRECAUTIONS: These appliances are not waterproof. They are fOf indoor use only and must not
be fixed where they could be exposed to dripping or splashing water. Objects containing liquids should not
be placed on or near the appliance. To prevent fisk of fire, no object with a naked flame should be placed
on or near the appliances, or the wiring to them.
FITTED MAINS PLUG: These appliances are supplied with a standard fused plug already fitted. If this is
not suitable, refer to the instructions below. In the unlikely event that you need to change the fuse in this
plug, a 3 Amp fuse to BS1362 carrying the ASTA or BSI approval mark must be used. Always re~fit the
plastic fuse carrier when replacing the fuse.
CHANGING THE PLUG: If the fitled mains plug is not suitable for the socket outlets in use, it should be
cut off and an appropriate new plug fitted. Wiring the New Plug: Any instructions supplied with the new
plug should be followed (these may state how much insulation to remove from the wires in the mains cord).
The brown wire must be connected to the live (L) terminal of the plug and the blue wire to the neutral (N)
terminal. Neither wire should be connected to the earth (E) terminal of a 3~pin plug (this appliance does
not require an earth connection). Ensure that the cord grip in the plug is correctly used and clamps the
sheath of the cord firmly
Fuse Rating: If the new plug is a fused type, the fuse fitted should be rated at not more than 3Amp.
Caution: The old plug should be destroyed promptly since it would be dangerous if plugged into a live socket.
2- Year Guarantee
Your amplifier is guaranteed against faulty components or poor workmanship for a period of two years
from the date of purchase. This guarantee does not cover accidental or malicious damage (including
damage from natural causes such as lightning) and will be invalidated by installation or use other than in
accordance with these instructions, repair or attempted repair other than by the manufacturer, or opening
or removal of the case. This does not affect your statutory rights.

VHF/UHF Single & Dual Output
Amplifiers with LTE800 4G filters
MSA111G
USER GUIDE
MSA121G
Introduction
These fully screened general purpose 1- and 2-way
amplifiers are ideal for boosting TV and radio signals in
the VHF and UHF frequency bands.
They each have a built in Lte800 4G filter which rejects
signals from 4G mobile phone transmitters in the
791-862MHz range.
Both units are suitable for handling terrestrial digital TV
(OTT) and digital radio (T-DAB) signals.
Amplification and distribution of digital signals requires
careful attention to signal levels for satisfactory results.

Installation Instructions

Important note: attention is drawn to the General Safety Precautions panel on page 4 which contains advice
relating to the safe installation and operation of these products.
Location
Choose a location for the amplifier from which it is convenient to run cables from the antennas and to the
receiver(s). Typical examples of suitable locations are a roof space or cupboard. In weak signal areas it is
helpful to keep the antenna cables as short as practicable.
Select a cool, dry location to install the amplifier. This means a location where the ambient temperature will
remain between -10°C and +40°C and which is free from risk of dripping or splashing water, etc. The fixing
location should allow adequate access to the equipment for wiring and maintenance. Clearance of at least
25mm should be allowed around front and sides of the unit for ventilation. More clearance will be needed to
the right of the amplifier to allow access for cables.
Fixing
The amplifier should be fixed to a wall or other suitable hard surface, using suitable screws and masonry
plugs (not supplied). The amplifier should not be left supported only by its wiring, nor should it be left resting
on a carpet or thermally insulating surface.
Electricity supply
Fixed wiring and connection of the electricity supply to these products should be carried out in accordance
with BS 7671 ('lEE Wiring Regulations').
Each amplifier is supplied with a fitted 13A mains plug. If this plug is not suitable, see the General Safety
Precautions panel on page 4.
As an alternative to the use of plug and socket connection, the amplifier may be connected to the supply
using a switched fused connection unit to BS 1363-4. A 3A fuse to BS 1362 should be fitted in the fused con-
nection unit.
If the amplifier is connected to the supply other than by means of its fitted fused plug or a fused connection
· unit, it must be protected by a non-time-delayed fuse or a Type B MCB at the distribution. board of rating not
exceeding 6A. An isolating switch should be provided near to the unit to allow it to be disconnected from the
supply when necessary.
Signal connections
Input and output signal connections are made using 'IEC' (IEC 60169-2) connectors. Good quality plugs
should be used, preferably of the crimp type. Plug inner contacts should always be soldered, unless of the
crimp type or provided with a screw terminal. The use of improvised crimping methods on solder type plugs is
not recommended.
