Labgear LMA113R, LMA209R, LMA125VR, LMA415VR Installation Manual

Introduction

The name Labgear has been associated
with quality signal distribution since 1932
and the current range of ampliers
continues to uphold that tradition.

All LMA masthead amps can carry analogue and
digital TV, Freeview, DVB-T and DVB-T2 HD TV signals and have:

• Improved gain atness delivering a better balance across
the performance range

• Lower noise gure for optimised signal quality

• Greater signal handling capacity to cope with more channels

• Better impedance matching and therefore improved signal
transfer from amp to cable

and now

• Class 3 ltering to provide a typical 45dB protection from
interference from 4G LTE800 transmissions

All LMA ampliers are compliant with the Radio Equipment
Directive 2014/53/EU and meet harmonised standard
EN 303 354 for product Type D, Class 3.

Labgear masthead amps are packed with features to
make installation easier, simplify fault diagnosis and deliver
a durable, quality solution, including:

• A sturdy metal mast clamp instead of a plastic cable tie

• LED power indication which assists fault diagnosis

• Tilt-out module for easier cable connection

• F-type connectors for better matching and security

• Solid housing with weatherproof seal

• Every masthead is supplied with a FREE metal f-type spanner

General Safety Precautions

•

To avoid risk of electric shock during
installation we recommend that the power
unit and all associated TV receivers, etc.
are isolated from the mains until the
installation is complete.

•

Fixed wiring for electrical supply to these
products should be carried out in
accordance with BS7671 (IET Wiring
Regulations).

•

Distribution systems supplying signals to
more than one household should comply
with the safety

requirements of BS EN60728-11.
This requires the system to be earth bonded
or the use of isolated outlets.

•

If you are in any doubt about an installation,

refer to a qualied aerial installer.

• When working on an installation outside,
beware of overhead power lines.

• Observe safe working practices, tread carefully
and ensure adequate lighting is available
in loft or roof space.

• Always follow manufacturer’s operating/safety
instructions when using tools/ equipment.

• Only carry out work outdoors at height if you
are competent in the use of ladders and
related access equipment.

• Always read and follow the manufacturer’s
instruction label afxed to the ladder.
