32 Element Digital Aerial with 

4 Room Distribution Kit

USER GUIDE

Introduction

Customer Careline  08457 573479

Congratulations on the purchase of your aerial and distribution kit. The kit is designed to receive and distribute 
both analogue and digital terrestrial signals around your home  to up to 4 TVs without loss of signal strength. 
This aerial has been manufactured to the standard required to get the best reception of digital terrestrial TV 
services (e.g. Freeview™). If the aerial is to be used for DTT reception check before installation at  
www.digitaluk.co.uk/ to confirm that your home is in a coverage area and to find where your local 
transmitter is. This kit contains all the items necessary for mounting the aerial to an existing mast or for 
mounting externally to eaves or a wall or mounting in a loft. This kit also contains digital type coax cable to 
ensure good reception.

Aerial Features

  Wideband – suitable for all UK TV reception areas, covering UHF channels 21 to 68 

  Receives both digital and analogue TV signals

  Perfect for use in the majority of locations although in very high strength signal areas an  

  attenuator may be required, or for very weak strength signal areas an amplifier may be needed

The aerial requires some assembly - please read these instructions carefully before beginning.

 

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.

 

A. Fitting the dipole assembly

1.  The dipole clips onto the central  
  boom. Ensure that the cable exit hole  
  (from the terminal box) faces the rear  
  of the aerial and that the locating stud fits  
  into the locating hole on the boom as  
  shown in Fig. 1. 

B. Rotating the aerial elements

1.  Rotate the elements about the  
  central fixing clip until they  
  ‘snap’ into an upright position as  
  shown in Fig. 2.

Analogue Terrestrial TV 

Snowy Picture

A faint, grainy or snowy picture is generally caused by 
a weak signal. Normally the TV transmitter will be a 
long way away. A possible improvement could be made 
by reducing the aerial downlead losses, installing a 
high gain aerial and by adding a low noise masthead 
amplifier or signal booster. In a small number of cases, a 
snowy picture can also be caused by a TV signal that is 
too strong.

‘Herringbone’ Pattern

‘Herringboning’ is generally caused by too strong a TV 
signal or by a local high power transmitter such as CB, 
amateur or taxi radio. Your TV sound may be affected as 
well as the picture. Using an attenuator will reduce the 
gain of an aerial signal and improve the overall picture.

Digital Terrestrial Television

Unlike analogue TV signals which can still be viewed 
under weak signal strength conditions, with digital 
terrestrial signals blocking/freezing and/or loss of digital 
picture and sound can be caused by insufficient digital 
signal and carrier to noise ratio. 

Similarly blocking and even a completely blank screen 
with no sound can result if the input signal to the set 
top box is too high.  The digital cliff refers to the rapid 
change from the picture and sound being perfect, to 
disappearing altogether.

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.

Intermittent Picture: 

Make sure all RF cable to 

connector joints are tight (both inner and outer) 
including all flyleads and surface outlet connections. 

To Prevent Overheating

The recommended clearances and other precautions 
given in the installation section of these instructions 
must be observed to prevent overheating.   
In addition, the amplifier should not be fixed where it is 
likely to become smothered by curtains or other fabrics, 
etc, or other thermal insulation materials in a roof space 
or similar building void. The unit should not be left 
resting on a carpet.

Cable Installation
Do not install cable - 

Closer than 50mm to mains or 

telephone wiring.
Under carpets in areas likely to be walked on regularly. 
With sharp bends at corners

.

Other Precautions

Apart from the aerial and cable all other parts of the kit 
are not waterproof and are for  indoor use only.  
They must not be fixed where they could be exposed to 
dripping or splashing water. Objects containing liquids 
should not be placed on or near the appliance. 
To prevent risk of  fire,  no object with a naked flame 
should be placed on or near the appliances or the wiring 
to them.

Fitted Mains Plug

The amplifier is supplied with a standard fixed plug 
already fitted.  In the unlikely event that you need  to 
change the fuse in this plug,  a 3Amp fuse to BS1362 
carrying the ASTA or BSI approved mark must be used.
