LAB450T USER GUIDE
Congratulations on the purchase of your high gain digital aerial. The aerial is ideal for the
reception of all available signals in medium, weak and fringe areas.
The aerial has also been designed to restrict bandwidth to prevent interference &
channel loss on TVs caused by signals from 4G mobile phone transmitters.
The aerial is of particularly robust construction to ensure a long operating life.

Installation Instructions
For optimum results install the aerial using double screened CAI approved digital coax cable
and screened coax outlets. You will need to fit the coax cable with an F type connector to
connect to the aerial balun.
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 (not supplied): Now, simply twist on an
'F' connector and trim 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.

3. Unfold the booms as shown above. To lock the booms in position turn both of
the two knobs on either side of the aerial in a clockwise direction through 180˚
making sure that the arrows line up with the locked symbol - see Fig. 4.
4. Next fasten the balun to the underside of the main central boom as shown in Fig. 5.
Make sure the balun is the right way round with the locating stud slotted into the
locating hole on the underneath of the central boom.
