Installation Instructions
For optimum results install the aerial using double screened CAI
approved digital coax cable (not supplied) and screened coax
outlets (not supplied). You will need to t the coax cable with an
F type connector to connect to the aerial balun.
1. Preparing the coax cable downlead: First slide the
rubber weather boot provided over the aerial end of
the cable. Strip the end of the cable as shown in
Fig. 1. Once you have stripped the cable, fold the
braid back over the outer sheath making sure that no
braid is touching the copper core, as this will cause a
short on the cable and you will not get any signal.
Also cut or tear away any foil shielding.
2. Twist the ‘F’ connector supplied on to the prepared
aerial end of the cable and trim the central conductor
see Fig. 2. Once you have installed your aerial and
run and secured the cable prepare the other end for
connection to an outlet or coax plug (not supplied).

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.
1. Unfold the booms as shown opposte. 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.

2. Next fasten the balun to the underside of the main
boom as shown in Fig. 5. Make sure the balun is the
right way round as shown in Fig. 4 and 8.
3. Fix the reflectors to the main boom using the brackets
and the bolt with wing nut supplied as shown below
in Fig. 6.

4.
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. 8.
Make sure that the coax cable is routed as
shown in Fig. 8 (through the middle of the
lower reector). Use insulating tape, to
secure the the coax downlead to the
reector and mast.

Use the tilting mast clamp supplied to x
the aerial securely to the mast. To adjust the
tilt angle loosen the two bolts, tilt to
horizontal and then re-tighten nuts (see Fig. 9).

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
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 qualied aerial installer.
