Hi, i live in quite a strong area, and the guy said in the shop that i could use an indoor areial to pick up freeview signals. I did a test with my loop areial on the top of my tv, and it picked up a few freeview channels, but not all of them. Which areial would you suggest would be the best to use indoors?? Please help me! Thanks!

I'm abt 30 miles from sutton coldfield
Picked up an unpowered one for 5.00 in Argos (end of line I think). Full signal on all Mux in Oxford.
At the mo there is no aerial, so if i could get one fixed up in the loft, that would be perfect and save me some money!

Could you give more information on your reception? Do you know that your getting your signal from Sutton Coldfield? Do you live to the South East of Sutton?
We are having a discussion of reception in the US and reception like you have is unheard of here. We typically have 1000 kW transmitters that are hard to recieve only blocks away and any transmitter with less than 100 kW is looked at as severly underpowered.
So your reception at 30 miles from a transmitter in Sutton at either 8 kW or 10 kW is seen as impossible.
Any information or photos of your antenna or info on the terrain between you and Sutton would be appreciated.

Yeah but whilst indoor reception might be unheard of, you do at least get a nice crispy HD picture unheard of here
Whilst some people can get decent indoor reception I don't think it's that common... many struggle to get good reception with a proper outdoor antenna.
Anyone in the US would be amazed at any kind of reception with the power levels you have.
Not going with HD is a political decision the UK made. Your modulation could deliver it as easily as what we have.
Our problem is that people can't reliably receive the signal with any kind of antenna at any power level if their locaton suffers from multipath.
What percentage of homes in the UK could get indoor reception if they did not already have a roof top antenna do you think?
Anyone in the UK would be amazed at the sort of picture quality you get when compared against the pixellated mess that some UK broadcasters transmit
If I remember correctly the BBC reckon that UK-wide indoor coverage is around 25% on our first floor (or your second floor
This compares to around 80% of the UK who can get reliable reception of at least some channels with the right roof-top antenna. Of course the UK DVB-T variant was never really designed for mobile/portable reception - in other European countries it has been.
The BBC R&D were interested in developing an indoor diversity antenna which would significantly improve reception on portable sets. http://www.bbc.co.uk/rd/pubs/whp/whp-pdf-files/WHP058.pdf
Either way an indoor aerial works for me here in the depths of Central London, surrounded by tall buildings and horrendous multipath.
How about impulse noise problems? The received wisdom in the US is that UK DTV is so plauged with impulse noise problems as to be unwatcheable.
8-VSB, our modulation does not work in the depths of New York City even with 400 and 800 kW ERP transmitters.
Your problem with pixelation is not related to your modulation right? It has to do with how many programs they are trying to mux into your 8 MHz channels.
Yes, too many programmes squeezed into limited bandwidth compressed with elderly broadcast equipment gives naff picture quality.
That was a serious problem back when the DVB-T services first launched in '98. A series of ERP increases (here in London some channels went up from 3kW to first 10, then 20kW) along with a subsequent change of parameters to 16QAM on some multiplexes (and better receiver design) has helped maked reception more robust.
It still isn't immune from it though, noticably towards the edges of the service area where field strength is low, or in homes with poor aerials the weaker digital signal (especially channels using the less robust 64QAM modulation) is still prone to impulsive interference.
