Martyn: If you had a good signal before with your aerial in horizontal polarity then turn the new one to horizontal and you should receive all the channels you had before.

Please can you advise me. The last three weeks we have had hardly any signal on some stations i.e. Dave, sky news and others. we have retuned two of our free view TVs, now we have lost sky news all together. The aerial is in the loft and has been there for over thirty years, obviously updated to a digital aerial.

We are at a lost as what to do next. My postcode is Po89au.

Is there a problem in this area?

Helen wraith: There is no such thing as a digital aerial, it's just a piece of metal that picks up signals and doesn't know or care what they are. If someone told you that you needed a new aerial specifically for digital TV then they were out to mislead you in to paying for a completely unnecessary new aerial if your old one was working fine for analogue channels. Retuning was a bad idea as you've now deleted the channels which were tuned correctly and leaves you with no easy way of knowing when the problem is fixed, unless you have another TV which still has Dave and Sky News showing in the TV guide?

The coverage prediction for your postcode shows that you should get a better signal for Dave, Sky News, etc if your aerial is mounted in the vertical polarity (i.e. with the little rods pointing up and down) rather than horizontal (little rods going side to side).

First of all, I should say that my television aerial is an indoor one - I don't have an outdoor aerial. Reception of the majority of Freeview channels is absolutely fine.
Some time ago certain channels began pixelating and they disappeared. I made the mistake of rescanning and lost them altogether. Essentially, they were the channels on the lowest-powered multiplexes. About two months ago I rescanned - and got some of them back. My favourite - TalkingPicturesTV - was still missing. A couple of weeks ago all of those low-powered channels again began pixelating - and, again disappeared. Mysteriously, last week they were back. Atmospheric conditions, perhaps.
I could wait for some good, stable weather and scan again.
There are inconsistencies - based on the spread of channels shown on this web page. I now have That's Solent again - that's on the lowest-powered mux (10,000W). I have all channels on the 18,400W mux - though they do pixelate from time to time. I DON'T have any channel on the 24,400W mux.
Is there any way of asking the staff in Rowridge why certain channels are placed on certain multiplexes? Why is it that I can receive the one channel on the 10,000W mux, but can't receive any on the 24,400W one?

StevensOnln1: Thanks Steven for getting back to me,. We do have two more TVs with free view on which we use mainly for virgin TV.. you are right in saying we have a good signal on most channels, on sky news there is a message weak or no signal coming up on screen. As it has been a problem for some time, is there any way of finding out when the problem will be fixed?

JohnH: Capacity on the commercial multiplexes (COM4-8) is sold to broadcasters on a commercial basis by the multiplex operators. There is no other logic to which channels are allocated where, other than what level of coverage each broadcaster is able/willing to pay for. The local multiplexes use a different transmission mode which is more robust and may explain why you can receive it but not COM7/8.

Helen wraith: There are no faults showing for Rowridge, and being a major transmitter broadcasting to over 600,000 homes it certainly wouldn't be allowed to have a fault unresolved for several weeks. The problem is at your end and no one else is going to fix it unless you take action yourself. If you've checked all your cables and connections and the problem is affecting multiple TVs then it's likely that the fault lies with your aerial or spliiter/amplifier or the cabling that distributes the signal around your home.
