Ewan Marshall: Yes, and once again you are quite correct, as admittedly depending on what you are receiving on (like in your own case) it can make a difference, but speaking in general terms virtually all modern TV / boxes on the market with bang up to date firmware can fully cope with offset problems, albeit I fully accept that some devices purchased as recently as about three years or so ago struggled a bit before they would lock on, although manufacturers software updates seemingly cured the problem on most, or in a partial sense on some depending on the level of signal they were receiving, the problem being worse on weaker signals.

We have a Sony Bravia which is 5 years old. Our aerial is a TRIAYUNIX52WIDE Band fitted in October 2010. Analogue is fifne but the digital sgnal at times breaks up to a very bad degree making programmes impossible to watch. We have two other digital televisions but they are served by a loft aerial and reception is good although we cannot receive the ssame amount of channels.
This aerial is very old. Can you please show any light on this? Will the changeover at Rowridge make any difference?

2019 2PB Thanks

Looking at predicted reception in Bransgore, am I right in thinking that after April 18th we will only be able to receive all mux's with a VERTICAL polarised aerial? The DigitalUK website seems to suggest so. It shows only 3 mux's still on HORIZONTAL polarisation after that date. Or am I going barmy?

Colin: The situation with Rowridge is that after switchover, it will broadcast horizontally and vertically.

The PSBs will be at 200kW for both polarisations.

However, the COMs will be 50kW horizontal and 200kW vertical.

This would explain the reason for the predictor's result.

I would wait and try it, particularly if you're going to have to get someone in to do it. The predictor should be treated as a guide and not gospel. It exists because of the demand for such a system but it's not possible to design such a system with total accuracy.

It's also often the case that a vertical aerial will pick up, to a certain degree, horizontal signals. So it could just be enough to save you having to have your aerial altered.

Colin: If I could add to what Dave said above, 18th April 2012 is the date when Stockland Hill COM muxes increase power and Crystal Palace begins high power working on the same frequencies. The Vertically polarised option is being transmitted at Rowridge from this date to help deal with interference problems anticipated in overlap areas and at times when the inversion effect allows signals to travel beyond their normal service areas.

Colin: Thanks for your replies - I'll wait & see then! I hope to be able to dispense with the outside aerial and use a loft one instead once the signal levels are boosted. I realise this is a retrograde step but if it works OK it makes it much easier to experiment between vertical & horizontal polarity & to maintain the antenna in the future.
