Labgear LMA113R User 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
