How high does antenna need to be for digital tv?

Will91w

Just bought a new digital tv aerial today and was wondering how high it had to be to receive signal. i cant put it on the roof so i need to mount it lower

Peter Rhea

It will depend on your specific location, as to how high (or low) you can get away with mounting the aerial. Things such as general signal strength, obstructions etc.

Some people can get away with indoor aerials at ground floor level, the attic might work, or you may have no choice but to mount it as high as possible outdoors.

Sam Russell

RTE NL suggest that the aerial should be at eaves height. This is easier than on the chimney.

Where is this 'suggested'? The aerial should, as a minimum, be at the height it needs to be to get an adequate signal, you can't just apply some arbitrary generalisation.

I have mine in my attic.

Receiving SAORVIEW
SAORVIEW is a free-to-air (FTA) service. Which means there are no monthly subscription fees or contracts to sign. In order to receive SAORVIEW you will need an aerial and a set top box (STB) or integrated digital television (iDTV).
Aerial
The majority of homes will receive SAORVIEW through your existing aerial, it is preferable that this be a roof top antenna. However in certain good reception areas a set top antenna may suffice but for reliable reception a rooftop is recommended, in almost cases, you will not need a new aerial.

The eaves are the roof bottom. Anyway, I thought my original reply covered all eventualities mentioned by RTENL in their documentation.

You didn't. There is no such thing as a digital aerial. You bought a new aerial plain and simple.

Sorry for quoting what it said on the box.

I think you'll need a 300ft guyed mast attached to the flute that Captain Picard played, first in his imagination, and then in real life, in the episode 'The Inner Light' from Star Trek: The Next Generation.

Seriously dude - how long is a piece of string....

In general, your neighbours are a guide to what is needed. If they have enormous aerials then you'll probably also need one too, if not you won't either.

I was reading it completely different, digital TV aerial - As in an Aerial for your Digital TV. As opposed to A digital aerial :rolleyes: .

Anyway Will91w, a lot of the time it will depend how close you are ie line of sight to the transmitter. If your close enough or have line of sight to the transmitter you may get away with an indoor mounted aerial, although this will be more susceptible to electronic interference. Ideally an external mounted aerial would be recommended or alternatively a loft/attic mounted aerial if signal is relatively good. Depends where you are really.

It was recommended in a couple of threads if you're going to go with an indoor aerial to try a cheap UHF indoor aerial (in or around the 5 - 6 euro mark), trial & error. Failing that a professional install would be required as these guys know best.
