Installation Instructions
Introduction
These technically advanced UHF antenna pre-
ampliers oer an unparalleled combination of low
noise, good input ltering and medium output.
The amplier units consist of fully screened modules
tted with f connectors. They are enclosed in a
moulded ABS weatherproong housing suitable for
outdoor applications.
They both have an integrated sturdy metal mast clamp
so that they can be quickly and securely tted to masts.
The ampliers also tilt by 45˚ to make the
attachment of f plugs to the sockets much easier.
The built in lter removes signals above 790MHz
emitted by Lte 800 4G phone transmitters and
picked up by the attached aerial.
Other features include
• Industry-leading noise performance
• Sturdy metal mast clamp
• LED power indicator, a useful aid to fault nding
• Inputs well ltered below 470MHz to minimise interference from Tetra transmissions
• The amplier is suitable for Indoor or outdoor use
• The LMA209F can be powered via either of its outputs

General Safety Precautions
•
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 axed to the ladder.
Power Supply
Both units require an independent 12VDC 30-35mA
power supply we recommend the use of the PSUF
12V, 100mA power supply unit with short circuit
protection and a fault indication LED which changes
from Green to Red. If using as a pre-amplier with the
LDA204L, LDA2061L or LDA2081L you do not need an
additional power supply, these distribution amps have
built-in line powering.
LMA113F
This 13dB model improves signal strength and C/N
in domestic and MATV systems with normal length
downlead cables.
This is ideal for use in digital installations where they
will enable the minimum recommended signal level
(45dBμV) to be delivered to the tuner and reduce the
likelihood of impulse interference problems.
LMA209F
This amplier with 9dB gain per port is ideal for feed-
ing two TV points from one antenna.
The downleads can be run mainly on the outside of
the building, making this a popular solution for retro-
t on older buildings.
It can be powered from either output, allowing exi-
bility in the power unit location.

Installation Instructions Installation Instructions
Fixing methods
Mount the amplier on a vertical section of the mast below the antenna using the built-in mast clamp
shown above.
The amplier will not be aected by proximity to the antenna, but reasonable clearance - about 300mm
- should be maintained to avoid disturbing the antennas performance. Otherwise for minimum sigal loss
mount as close to the antenna as possible.
Signal connections
Type-f connectors provide a reliable low-cost method of connection with excellent screening integrity and
impedance match. Select the appropriate male connectors to t the cable type used.
This method of connection is superior in all respects to saddle-and-clamp types that it replaces.
Good quality double screened coaxial cable to EN50117-2 should be used, ideally in conjunction with high
quality crimp on connectors.
Connectors should be properly tted in accordance with the manufacturer’s instructions, using a suitable
crimping tool.
For easy connection the amplier module tilts by 45˚ making it easier to screw on your F connectors.
F connectors should always be tightened very gently with a spanner. Leaving them nger tight can result
in unwanted signal ingress or leakage, as well as suck-outs in the frequency response.
After making your connections ensure that all cables are aligned with the slots in the housing before gently
closing the housing. Make sure the locking catch on the rght is closed securely
Connecting to a power supply unit (PSU)
We recommend that you use a PSUF - 12V 100mA power supply with Type-F connections.
However alternative 12V power supplies can be used providing they supply enough current, see the
specication table below for current requirements for each amplier. Read carefully the instructions that
come with your PSU before installation.
The PSU should ideally be xed to a wall, skirting board, mounting board or similar hard surface.
A ventilation gap of at least 25mm should be left around the front and sides of a PSU.
Do not leave the power unit resting on a carpet.
Do not install the power unit where it may become smothered by curtains or other fabrics.
If you are installing the power unit in a roof space ensure that it is not covered by thermal insulation
materials.
Signal connections are made to the coaxial sockets on the right-hand side of the power unit. Good quality
coaxial cable to EN50117-2 must be used. Labgear recommend the use of CAI“benched marked” cable.
•The down lead from the masthead amplier must be connected to the socket marked‘IN’.
•The signal output from the socket marked‘TV’ is connected to the receiving installation
(satellite receiver, VCR, TV, etc.) or to the input of the cabled distribution system.
Connections
Connection to the PSU are usually made using type-f (male) connectors.
The use of high quality crimp connectors is preferred.
F type connectors should always be tightened very gently with a spanner. Leaving them nger tight may
result in unwanted signal ingress or leakage, as well as suck-outs in the frequency response, alternatively
do not over tighten as this could damage your PSU.
General Safety Notes
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 (IEE
Wiring Regulations).
Distribution systems supplying signals to more than one household should comply with the safety
requirements of BS EN50083-1. This requires the system to be earth bonded or the use of isolated outlets.
