 AERIAL SELECTION & WHY? At the moment, the TV programs you receive are transmitted in groups. A different group is transmitted from each transmitter to avoid interference between the transmitters. The aerial you have on your property will be designed to receive as much signal from the group your transmitter is using. With digital TV, only one group is required for all transmitters as the digital signal is not affected by interference from other transmitters, leaving the Government several groups to sell off to mobile phone companies etc… As the Government has not yet decided what group it is going to use, your installer should be using a wide band aerial that covers all groups. If the Government uses a group that is far away from the group your aerial is designed to use, you could experience reception problems, where with a wide band aerial this will not occur.  TYPES
OF AERIAL: NOT SUITABLE for
digital TV receptionA customer said to me: “An aerial is an aerial”. That is the problem which you the consumer faces, because when an aerial is erected how do you, the customer know that the best has been erected for your digital viewing requirements? The aerial pictured right is called a contract aerial and is the type of aerial most of us are familiar with. This type of aerial will receive a digital signal, but DOES NOT meet the new standards required for the long term reliability of digital TV reception.   Far left: This cable prepared for connection DOES NOT meet digital standards. Left: This method of connecting the cable to the aerial DOES NOT meet digital standards.  TYPES OF AERIAL:
SUITABLE for digital TV receptionThe type of aerial pictured right is one of the types of aerial which DOES meet the required standards for digital TV reception in all areas. The CAI approves the benchmarked quality types of aerial, cable and connections that TST installs, to meet the new digital standards for all new TV aerial installations.   Far left: This cable prepared for connection DOES meet all the standards for digital TV reception. Left: This method of connecting a cable DOES meet all the standards for digital TV reception.
