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.
For optimum results install the aerial using double screened CAI approved digital coax cable
and screened coax outlets. You will need to t 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.

5. The reflector bracket rotates through 90˚. When boxed it is usually in the
horizontal position as it takes up less space. Before attaching the reflectors
the bracket must be rotated into the vertical position as shown in Fig. 6.
If you need to rotate the bracket push it towards the front of the aerial to
unlock, then rotate clockwise through 90˚ using the arrow as a guide then
pull the bracket back into it’s original position. *
6. Slide the reflectors into the reflector bracket until the locating studs click
into place as shown in Fig. 6.*
7.
Use the tilting mast clamp supplied to x the aerial securely to the mast.
Adjust the tilt angle to make sure the aerial is horizontal, see Fig. 7 and 8.
8. Connect the aerial downlead to the‘F’ socket on the aerial balun
(be careful not to over tighten the F connector as this will damage
the balun). Ensure that the weather boot is correctly secured over the
‘F’connector and socket - see Fig. 9.
Make sure that the coax cable is routed as shown in Fig. 9 (through the
middle of the lower reector).
Use insulating tape, to secure the the coax downlead
to the reector and mast.
8. Fine adjust the tilt and direction of the mast clamp to tune for
optimum reception.
*Please note that when the reector locating studs have clicked into place the reector
bracket is locked into position. If you are unable to push the reectors in completely to locate
the studs make sure the bracket has been pulled right back.
Troubleshooting
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 precau-
tions 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.
