LABHG420 Wideband Digital Aerial
Congratulations on the purchase of your digital outdoor aerial. The aerial is ideal for the
reception of all available signals in strong and medium strength signal areas.
• Ideal for weak reception areas
• Tilting mast clamp for easy adjustment
• Easy dipole assembly
• Electronic 75Ω balun
• Connection: F type
Installation Instructions
Fig. 1
For optimum results install the aerial using double screened CAI approved
digital coax cable and screened coax outlets. You will need to fit 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 the central conductor.
Aerial Assembly
Attach the 8 elements to the boom, the arrow on moulding must
point to the front of the aerial, away from the reflector panels.
Ensure the pin on each element moulding locates in the appropriate hole in the boom( see opposite).
Unscrew the wing nut from the dipole assembly and attach the
dipole to the boom, securing with the wing nut as shown opposite. The F socket connector must be pointing down and the flat blade director should face towards the front of the aerial.

Assemble the two reflector clamps to the boom and secure with the coach bolt and wing nut provided. Slide one reflector panel into the slot until it clicks into place and can not be pulled out.
Note:- Ensure panel is centrally mounted.
Repeat the same procedure for the second reflector panel.
Fit the assembled aerial onto the mast using the mast
clamp provided with the aerial, the mast clamp is suitable
for mounting on to 25 – 50mm diameter masts.
Using the tilting mechanism adjust the aerial to horizontal
and tighten hexagonal nuts.
Connect co-ax cable fitted with F plug (co-ax cable and F
plug not supplied), to F socket outlet on dipole (be careful
not to over tighten the F connector as this will damage the
balun). Ensure the weatherproof boot is fitted to the cable
and pushed over the connection.
Using PVC insulating tape, tape the co-ax lead to the aerial
as shown opposite.
Do not allow the cable to touch the aerial boom at any
point.
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.
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.
