Installation Instructions
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 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.
The plate for the bracket has extra holes drilled at right angles to allow vertical mounting of the aerial.
The aerial comes fully assembled.
If mounting on an existing mast check that the mast is in good condition and rmly xed.
3. Use the mast clamp supplied and tighten the wing nuts
tightly until the aerial is held rmly in a
horizontal position as shown in Fig. 3.

Connect the aerial downlead to the ‘F’ socket on the
back of the aerial (be careful not to over tighten the
F connector) see Fig. 5.
5. Slide the weather boot over the ‘F’ connector and
socket to make a good seal - see Fig. 6.
Make sure that the coax cable is taped to the mast.
Use insulating tape, to secure the the coax downlead
to the mast.

Finally connect the aerial to your TV or other reception
device and check the picture. Fine adjust the direction
of the aerial to obtain the optimum signal reception.
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.
