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 fi rst, 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 qualifi ed 
aerial installer.

C. Coaxial cable routing and 

  fi xing 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.

1x  Central boom: assembly square aluminium (L) approx 865mm 

 

with 7x curved aluminium elements 

2x  Refl ector booms: Square aluminium (L) approx 160mm with 

 

3x refl ector elements each: curved aluminium (L) approx 425mm

1x Bow tie shaped dipole and printed circuit balun

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 fi rmly fi xed.
1.  Using the clamp supplied fi x the aerial to the mast - see Fig. 5 & 6. 
2.  After the aerial direction has been fi ne tuned for best reception 
 

tighten nuts fi rmly until the aerial is securely fi xed to the mast.

Can also be loft mounted.

what DTT channels should be available locally and to fi nd

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 fi t one please follow the 
wiring instructions shown below.
