•Receives both digital and analogue TV signals
•Suited for strong signal strength areas only
The aerial requires some assembly - please read these instructions carefully before beginning.
Main Features
Congratulations on the purchase of your wideband aerial which is designed to receive both analogue and digital terrestrial signals.
This aerial has been manufactured to the standard required to get the best reception of digital terrestrialTV services (such as Freeview™). If the
aerial is to be used for DTT reception check before installation at www.dtg.org.uk/retailer/coverage.html to confirm that your home is in a coverage
area and to find out where your local transmitter is.For optimum results install the aerial using double screened digital coax cable and screened
coax outlets.

1. Using the reflector clamps,screw and large wing nut,fix
the reflector assemblies to the main aerial boom as
shown in Fig.1 & Fig.2.
2. Check that the reflector clamp tabs locate in the holes
of the reflector boom sections and that the wing nut
is tight as shown in Fig.2.
2. Ensure that the reflector elements are facing towards the
front of the aerial (convex surface forward).

Please Note: Coaxial cable,mountings and masts are not supplied with this aerial.You will need to select these from the range
available according to the specific requirements of your installation.The quality of the coaxial cable used is as important as
the quality of the aerial and you should make sure that if it is not specifically marked as suitable for digital TV it is of the same
quality as that used for digital satellite installations.

1. Before preparing and stripping the cable ready for connection,
feed the coaxial cable through the hole in the terminal cover.
2. Prepare cable as shown in Fig. 3..
3. Feed prepared cable through the braid clamp and thread the
centre wire through the hole in the central terminal as shown
in Fig. 4.
4. Clamp the cable braid securely first, then tighten the screw on
the central terminal.Trim any stray braid that might come into
contact with the centre wire or central terminal.
5. Replace terminal cover carefully and securely making sure that
the cable is not trapped or kinked.
B. Connecting coaxial cable
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 qualified
aerial installer.

C. Coaxial cable routing and
fixing aerial to a mast
For optimum performance it is very important that the coaxial cable
should be routed as shown in Fig. 5.
DO NOT ALLOW THE CABLE TO TOUCH THE AERIAL
BOOM AT ANY POINT.
PVC insulation tape can be used as shown to hold the cable in place.

Coax plug wiring instructions
1 Unscrew coaxial plug housing and slide cap
over cable.
2 Strip 23mm of cable outer sheath.
Gather copper braid, wrap around outer
sheath, slide claw over braid and crimp.
3 Strip 18mm of inner insulation to leave 5mm
exposed
4 Undo screw on plug/clamp, slide clamp over
inner wire & tighten screw. Reassemble plug

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.
If mounting on an existing mast check that the mast is in good
condition and firmly fixed.
1. Using the clamp supplied fix the aerial to the mast - see Fig.5 & 6.
2. After the aerial direction has been fine tuned for best reception
tighten nuts firmly until the aerial is securely fixed to the mast.
Can also be loft mounted.

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.
Troubleshooting
PLEASE NOTE: A coax plug is not included with
this aerial. If you need to fit one please follow the
