Labgear LDA204L Installation Instructions

Installation Instructions

Introduction

These fully screened general purpose 

4, 6 and 8 way amplifiers are ideal for  

distributing TV and FM DAB radio signals. 

Separate inputs for UHF TV (470-790 MHz)  

and for FM DAB (40-270MHz).  

The 6 and 8 way versions feature a higher  

gain “FULL”  (18dB) output. This may be  

used in conjuction with additional passive  

accessories (taps and splitters) 

to allow additional outputs to be fed or 

to feed other distribution amplifiers. 

Please Note: If the full power socket is not  

being used it must be terminated with the 

75Ω terminator supplied.

In weak UHF signal areas, or where a long 

downlead cable is required, it may be desirable to 

use a masthead preamplifier mounted close to the UHF antenna. 

These multi-way amplifiers feature a built-in 12V line powering 

on the UHF input; ther is no need to use a separate power unit for 

the masthead amplifier. The built-in line power is rated at 25mA (fully short  

curcuit-proof) and is compatible with Labgear masthead preamplifiers.  

The masthead gain should be keep to a minimum and genarally only needs to exceed the 

downlead cable loss. A single stage 13dB gain masthead (LMA113F) will be suitable for the 

great majority of applications. 

All units are suitable for direct amplification of digital terrestrial TV (Freeview™) signals.  

When connected directly to a UHF aerial the integrated filter remove any signals from Lte 800 

4G mobile phone transmitters picked up by an attached antenna. 

Applications

Applications include the following:

•  Simple multipoint distribution of radio and TV signals.

•  The Full Power output on 6 and 8 way units makes these units ideal for use in larger  

  homes and flats

Please Note: These units have no IR return path and require a digital bypass to be fitted to 

enable remote control of Sky™ equipment via the RF2 Output. When using these amplifiers 

with a Sky Digibox, the amplifier must be fed from RF OUT-2 socket of the Digibox.

To view satellite RF2 output TVs require an analogue tuner.

General Safety Precautions

To Prevent Overheating

The recommended clearances and other precautions given in these instructions must be 

observed to prevent overheating. In addition, units should not be positioned where they 

are likely to become covered by curtains/fabrics or thermal insulation materials in a roof 

space or similar building void. The unit should not be left resting on a carpet.

Other Precautions

These appliances are not waterproof. They are for indoor use only and must not be posi-

tioned where they could be exposed to dripping or splashing water. Objects containing 

liquids should not be placed on or near the appliance. To prevent risk of fire, keep the 

unit and attached wiring well away from naked flames.

Fitted Mains Plug

These appliances are supplied with a standard fixed plug already fitted. If this is not  

suitable, refer to the instructions below. If you need to change the fuse in this plug,  

a 3Amp fuse to BS1362 carrying the ASTA or BSI approved mark must be used.  

Always re-fit the plastic fuse carrier when replacing the fuse.

Changing the Plug

If the fitted mains plug is not suitable for the socket outlet in use, it should be cut off 

and an appropriate new plug fitted. Any instruction supplied with the plug should be 

followed. 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 no more 

than 3 Amp. Caution: The old plug should be disposed of promptly since it would be 

dangerous if plugged into a live socket.
