I presume you mean to ask how to check the reception from your aerial? Arial is a type face used in printing, etc. A Receptionist works in the front office of a business. I presume you relied on predictive text, which has serious limitations in any technical sphere.

To anser the questio I think you are asking, your TV set will have a facility for manual tuning and that will show a signal strength reading - check your User Manual for how to do that. DO NOT perform any manual tuning, merely read the numbers for signal strength. Ideally they should be between 60% and 85% on all channels. Any higher or lower will give reception problems such as picture break up, loss of sound or even total loss of a channel.

I'm on the Sandy Heath transmitter (Cambridge) which from maps shows we are close to the edge of the signal. We switched from Sky to BT six months ago and started to loose the picture when planes from military base flew over - not really to much of a problem. Over the last 6 weeks the picture has started to break up a lot on the HD channels. So bad that we cannot watch mainstream channels in HD. I bought a booster box and fitted it yesterday but it has made no difference - last night was fine, but this morning it's poor again. The signal strength is 100% on all channels, but the picture quality is all over the place and every 15 seconds it drops to zero and the picture disappears. Do you think an attenuator would help, could the signal strength be too high?

YES!

100% is far too high. But check your system first, without a booster, looking at which transmitter you should be on (Sandy Heath looks fine), and then look at signal strength. If your losing channels, its a classic sign of a problem with your system. Buying a booster can offset that, but wont solve it, and might actually cause more problems.

Start with cables and connections - it might as simple as a dodgy connection.

Can our property receive Freeview HD on an indoor aerial?

Which aerial is the best to install?

lynda: Most indoor aerials are rubbish (they are usually little more than a piece of wire sticking out of an amplifier) and will only give good reception if you have a strong signal. If you provide a full postcode you'll get a coverage prediction which will allow further advice to be given.

Canvey Island

I have a problem i have a humax fvp=5000t freeview, using the arial settings roof top to Blubell hill Trasmitter as the arial guy said it was the better signal instead of the London Crystal Palace transmitter, arial was put up about 4 years ago, i have someone elses arial which is faulty and in strong winds it leans on my arial, i think its made my arial move a bit, My problem is i now get a 1 or 2 second picture freeze on most channels,
I live on Canvey Island in Essex, post code is ss8 7rn . On checking your map and using predicted signal for ss8 7rn they all come up with the London Crystal palace Transmitter, Is This picture freeze due to faulty humax or is it down to not being lined to the right transmitter.Im due to get a new 4g tv so would i be better of getting a new Arial to replace my old one. Thank you

peter rance: Check your signal strength. Humax have sensitive tuners, and so if your getting too strong a signal (80% plus), then you will get breakup. Thats easily sorted.

If its too weak, then at least you can narrow down the possible causes.

peter rance: 81% is too high, as you can see if you look at the page 'too much of a good thing'.

Thats why you have a problem - every so often the tuner is being overwhelmed by the signal strength and breaking up. Its not a fault with the PVR (and anyway, its only Panasonic and Humax that really supply PVR's these days) but simply a need to damped down the signal a little.

I use fixed strength attenuators which I bought off Amazon, which can be fitted together to cut the strength by a varying amount.
