Darryl: my interpretation was different to yours. I took 'cross shape, due N, S, E, W' to mean that the signal was concentrated in these specific directions and 'nominally omnidirectional' to mean that it was not truly omnidirectional.

I've just found these posts, so apologies if I am repeating earlier questions. Like Graeme, my HD channels have gone. My aerial is pointed at Blackhill too. I was getting HD until about two weeks ago, now nothing. When I do the manual search on my Humax pvr Fox t2 I get zero signal strength on channel 59. I'm in Dollar (FK14). Any suggestions?

Scott: It's what's called a 'skew-fire' array. The low-power DTT aerial at the top of the mast is also a skew-fire array, and so is the old analogue array for BBC, STV and C4 analogue. The radiation pattern for the three different aerials should be much the same, although some people could have problems with the terrain on C5 and HD because they're further down the mast.
You can see pictures at http://www.thebigtower.com/live/BlackHill/61P21000306062.htm
They have built a new mast, and I don't know whether it's in service, when it went into service if it is, and which services transferred.
Since the reports of problems with the HD service seem prevalent, try going through the BBC interference page. Go to BBC - Reception problems and enter your own postcode. (I've copied that link from John P's post.) If you go far enough through the wizard, you eventually get to a form where you can email them.

Hi
I live in Ayr, Ayrshire. The reception on 505 MHz is terrible but everything else is ok. I have a bt vision system and when I check the signal strength and quality it is at roughly 60% on all channels except channels using 505 MHz the strength is good but quality is roughly 5%. Does anyone else have the same problem?

Neil Morgan: No services are provided on 505MHz. C25 is on 506MHz. I would see Single frequency interference | ukfree.tv - independent free digital TV advice .

Thanks for the reply but it def says 505mhz. Any idea what might be causing the problem, I have unplugged everything except the tv and bt vision box.

Have had problems with the HD channels on freeview over the past week. I use a One For All indoor aerial, and even though its not perfect i footered around with it when first got it and as long as the thing is tilted i get between 68 and 72 signal strength with, what my tv says is, 1700 and 1920 bit error level.
As long as this error level does not go up to 2000 i get a stable picture however this past week is been acting up and now i am getting full bit error level (2000) so not picture. Its just a bit of a co-incidence that all these HD signal problems are happening at the same time with the Blackhill transmitter.

Anthony: As a general rule, you need a rooftop aerial for reliable Freeview reception.
