Q: THE most common question with an aerial installation is “How much?”



A: The simple answer is............... no idea! All installations, like car repairs, are different and a call out is the best way to give a quotation. In the Perth area a quotation is usually free.



Q:The postcode checker tells me I can’t receive the full service freeview!



A: The postcode checker is pretty accurate but not 100%! Give me a call and I can advise, all is not lost!



Or we can install a “freesat” system giving up to 145 television and radio services including the high definition services from the BBC and ITV.



Q: How do TV aerials work?



A: Television waves travel in straight lines rather like light rays and don’t bend much around obstacles. So, wherever you live, your receiving aerial should be outdoors, as high as possible, and in the clear, so that it gets the best direct signal. It is extremely important to use a good quality aerial from a reputable manufacturer to avoid the risk of poor reception. As television reception can vary dramatically over distances of a few feet or even a few inches, the precise location of your aerial can have a big influence on the quality of your picture. Outdoor aerials do not last indefinitely. If reception begins to deteriorate, it could be due to corrosion of the cable connections inside the aerial junction box. The aerial may even have been knocked off alignment or broken by strong winds. Inspect the aerial for mechanical damage, and check the cable downlead to make sure it has not deteriorated or been broken. Sunlight can cause it to become brittle, while the ingress of water causes a large loss of signal to the TV set. Aerials and downleads may need to be replaced more often in exposed, coastal, or industrial areas.



Q: I’ve heard there are eight “multiplexes” for freeview digital reception. What does this mean?



A: One multiplex transmits the compressed digital information for say up to eight television stations in the space that only one analogue station occupies! The entire output of say ITV can be transmitted on one multiplex, confused? More info on what’s transmitted visit the dtg site.



Q: What are the digital freeview channel allocations for the Angus (Tealing) transmitter?
