Question on TV Aerials?

Question

My loft TV Aerial is a UHF type my question is will I have to change it if I get a freeview digital box, if so what type will I need and how much should I expect to pay for it please?

Answer 1

It's difficult to tell from the information you've given, as there are so many variables to consider.

For example, are you in an area that has a good digital reception? If not, it doesn't matter what aerial you buy, it won't work digitally.

Also a good analogue signal does not of itself guarantee a good digital signal.

I would recommend borrowing a friend or neighbour's Freeview box and test that on your aerial. The outcome of that will determine whether you need a new aerial or not.

I can't give an accurate prediction as to the price of a replacement aerial, as it will vary between companies and districts, as most things do. However, to get an aerial that's powerful enough to get a digital signal will probably cost a minimum of £80, including fitting. You can buy aerials cheaper, but I couldn't say that they'd support digital signals.

Answer 2

It depends on the signal strength and quality in your area. With analogue TV as the signal weakens the picture gradually gets snowier until no longer watchable. With digital there is a sudden point at which the signal is too weak to be usable. This is called the edge of the cliff effect. Even with a good outdoor aerial you may not get all Freeview channels because until the analogue is switched off, some freeview channel groups are being transmitted out- of -band and need a wideband aerial to receive them. Also digital is not on full power yet until analogue is switched off. I would expect the cost of a new outside aerial to be around £80 for a standard one including labour, cable and fittings; considerably more if you need a fringe aerial and/or booster (in a weak signal area).

Hope this helps.

Answer 3

As with any Aerial reception of UHF signals what effects reception the most, if the antenna is the right type and connected properly, is the surrounding transmission sources. Everything from localized within 300meters to 3miles radius.
Look around your neighborhood, above the rooftops, in the distance, if you see cellular/mobile towers or any kind of Radio towers, you can expect interference. Many tower owners lease space to facilitate every conceivable kind of RF transmission you can imagine, many overlap the UHF frequiency range : UHF 300–3000 MHz
1 m – 100 mm television broadcasts, microwave ovens, mobile phones, wireless LAN, Bluetooth, GPS and Two-Way Radios such as FRS and GMRS Radios.

Something to consider:

Answer 4

Assuming your current analgue reception is ok, then a Freeview box should work with your existing TV aerial.

Answer 5

the in hassle-free words applicable answer on your question without expertise of the position you stay is: The connector has diverse names in diverse international places because it isn't an similar connector in all international places. In u . s . a . and in international places making use of an similar well-known it really is an F-connector (male for the cable and lady for the television set or VCR connection). In different international places it ought to correctly be what we human beings call a PL-259 for the male and a SO-259 for the female. So it varies by united states. You call it an aerial and we call it an antenna.
