Installation Instructions
Features include:
• 12dBi Gain
• F type connector for secure and easy connection
• Fast simple assembly
• Compact pack for easy transportation
Congratulations on the purchase of your LABGT12A aerial. The aerial is ideal for the reception of
Group A signals in strong and medium strength areas. The aerial design has been tuned to
maximise reception of channels 21 - 37 and reject signals on other frequencies including signals
from Lte800 4G mobile phone transmitters which can interfere with digital TV channels.
For optimum results install the aerial using double screened CAI benchmarked digital
coax cable and screened coax outlets. You will need to t the coax cable with the F type
connector supplied to connect to the downlead (not supplied)
to the F socket on the aerial.
1. Prepare the Coax Cable: Firstly fit the rubber weather boot
provided, to the aerial end of the cable. Strip the end of the
cable as shown in Fig. 1. Once you have stripped the cable,
twist the braid and pull it back on itself, make sure that no
braid is touching the copper core, this will cause a short on
the cable and you will not get any signal.
2. Fitting the F connector: Now, simply twist on
the ‘F’ connector supplied and trim the central conductor.

For best results the aerial should be mounted on an outdoor aerial mast and pointed in the direction of the nearest
transmitter* making sure it is in a position where the transmitter signal will not be obstructed by nearby trees and buildings.
If you are in any doubt about the direction in which the aerial should be pointing or the orientation of the aerial (horizontal for
main transmitter, vertical for relay transmitter) check your neighbours’ aerials.
12 Element Digital Group A Aerial
The aerial requires some assembly.
If mounting on an existing mast check that the mast is in good condition and rmly xed.

3. Slide the reectors into the
sockets mounted on the
central boom until they click
into place as shown in Fig. 3.

4. If not already in position slide the mast clamp on to the aerial
boom and then slide the clamp into position on the mast.
Make sure the aerial is pointing in the direction of the nearest
TV transmitter now tighten the wing nuts until the aerial is
securely fixed into position, see Fig. 4.
5. Connect the aerial downlead to the ‘F’ socket on the
underside of the balun (be careful not to over tighten
the F connector) see Fig. 5.
6. Slide the weather boot over the ‘F’ connector
and socket to make a good seal - see Fig. 5.
7. Make sure that the downlead is routed as shown in Fig.5
making sure the lead doesn’t touch the reector.
Use insulating tape, to secure the coax downlead to
the mast.
8. Finally connect the aerial to your TV/set top box
and check the picture. Fine adjust the direction
of the aerial to obtain the optimum signal reception.
No picture:
Check all connections from aerial to TV.
Poor picture:
Check all connections from aerial to TV.
Check aerial is properly aligned to the correct transmitter.
If the aerial has been loft mounted try mounting outside.
Make sure new digital coax cable has been used
throughout the installation.
Check the transmitter signal is not obstructed by nearby trees
or buildings.
If in a very weak signal area or for long cable runs,
installing a masthead amplifier will improve the signal.
If in a strong signal area the signal strength may need to be
reduced by fitting an attenuator.
Caution
When mounting the assembled aerial, always observe safety
precautions and use the correct equipment.
Unless you are competent in the use of ladders and other
access equipment, do not work outdoors at roof height.
If in any doubt, refer to a qualied aerial installer.
