Also, when you say vertical aerial polarisation, do you simply mean that you turn the aerial through 90 degrees so that the aerial prongs point up and down? This would also mean that all other parts of the aerial assembly would be turned through 90.

adrian_tcp: Yes, the prongs (directors), the dipole (where the coax is connected) and the reflector (the plate or set of rods at the back end) are all vertical. The boom of the aerial should be horizontal or have a very slight tilt up towards the transmitter.

adrian_tcp: As far as the aerial mounting is concerned its a case of the entire aerial being in effect being turned on its side, because the vertically polarised COM signals from Rowridge radiate on 200Kw whereas on horizontal its only 50Kw, however the fact of you having said that you suffer from pixilation on the PSB2 & PSB3 muxes does not give much hope as far as glitch free reception is concerned, but though it depends on what you observe on a signal quality check, because if both the strength and quality are seen to fluctuate within a certain range but never at any time rapidly dip to near zero and back again, then keeping the signal running at a high level can in many cases help to keep pixilation to a minimum, but if the quality is seen to frequently dive to zero and back then no matter how fast it does it the picture will suffer.

The problem is, that when that sort of thing occurs there is virtually nothing that can be done at the receiving end that will help the situation as the problem is outwith local control, as its basically caused by the signal path from the transmitter to the receiver being affected by obstructions along the way, and with the most commonly experienced reason being trees and such likes even if they have shed their leaves, and with quick check over the signal path between Rowridge and your area indicating quite a number of hazardous areas for RF signals.

However, I suggest that you carry out the check referred to, that is on the assumption that your TV or box does offer both a strength and quality indicator and giving an update on the results of the check.

By the way if the brown coax referred to is of the thinner variety then it should be changed to a satellite grade such as WF100, but if its the thicker variety with a woven copper mesh that does not separate easily then its most likely perfectly OK.

Thanks. I only have strength, not quality. However, on Film4 which is one of the worst, signal strength is 68-72 but Bit error level is max at 2000, whatever that means. ITV2+1 is 58-62 but no but errors and not pixilated, so is there anyway of reducing the bit errors, like having 2 amplifiers in series?

My XP media centre PC tuned to Rowridge can only get the program guide up to the end of this year.
In spite of retuning and reloading all stations the program guide loads no data for 2013 and therefore now has no search facility.

Frederick love: Well... one option is to take the cheap Windows 8 upgrade
Buy Windows - Microsoft Windows
(£24.99) and then
Add features - Microsoft Windows
(free) - I will cost you and a couple of hours.

Briantist: It's a problem with my Vista media centre EPG as well, seems a lot of people are reporting the problem on the internet - I doubt buying Win8 will solve the issue.

Briantist: Win7 should be ok for a 7 day EPG as that uses broadcast data, unlike XP and Vista.

Found a thread on it, and it's also been reported to Microsoft: View topic - Guide Updates - Download Issues

Resorting to trying EPG Collector to see what happens (instructions at the end of that thread).

Michael: The Win7 (and Vista if you have installed the upgrades - Freeview news | ukfree.tv - 10 years of independent, free digital TV advice ) Media Center can use either the internet-delivered (from DigiGuide) or Freeview-delievered listings.

From the "TV Programme Guide" screen, right click on a channel (like "1 BBC One") and choose "Edit channel". You then see...



And select "use listings from broadcaster".

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
