Aerial FAQ's    Satellite FAQ's    Remotes FAQ's 

Q.1 What type of aerial do I require at my location?

A.1 Gain and aerial choice depend on the proximity to the transmitter and can also depend  the type of installation. IE Loft or outdoor.  An outdoor installation will enable a clear line of sight to the transmitter, and will generally perform better than a loft installed aerial. To check the distance from the transmitter and to obtain a compass bearing to the transmitter please check the following website: http://www.digitaluk.co.uk/postcodechecker/

The greater the distance from the transmitter, the higher the gain of aerial is required. The shorter the distance to the transmitter the less gain is usually required.

Q.2 Which aerial produces more gain a 32 element, 48 element or a 52 element version?

A.2 Generally the higher the number of elements, the more gain the aerial will produce. This applies to the 32, 48 and 52 element aerial.

Q.3 What can I do to check the level of signal and quality of signal?

A.3 In a digital set up, the majority of set top boxes and TV's with inbuilt digital tuners will have a signal strength and a signal quality meter contained within in the set up menu.

Q.4 What can I do to improve a weak signal?

A.4 To increase the gain of an existing set up fit a Signal booster or Mast head amplifier

Q.5 What can I do to reduce gain?

A.5 Fit an inline attenuator

Q.6 Are the 32, 48 and 52 element aerials compatible with Digital and analogue TV?

A.6 Yes the aerials are fully compatible with existing analogue and digital TV set ups . The aerials are CAI approved, considered suitable for Digital equipment and are also approved to the Digital Tick Scheme. Please visit http://www.dtg.org.uk/ for further information.

Q.7 I have been told that I need a wideband digital aerial to get digital tv in my area. Is this correct?

A.7 If you are having problems receiving digital TV from existing set ups then an upgrade to a wideband aerial is usually recommended. Existing group aerials may be unsuitable to receive the full bandwidth that digital TV is broadcasted on now and in the future.
