VHF/UHF Single & Dual Output  

Amplifiers with LTE800 4G filters

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.

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.

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.
