The symbol shows the location of the Midhurst (West Sussex, England) transmitter which serves 94,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

I live in Shanklin on the Isle of Wight and my aerial before swithcover was pointing at Midhurst and I had every channel going. I have one of these in the loft Security Warning

All was fine until switchover. After switchover I can still get PSB1 and 2 at full quality and strength but com4 comes and goes and com5 and 6 are no longer there.

With the aerial still pointing to Midhurst I can pick up psbn 1 and 2 from Rowridge, this means the aerial is a full 90 degrees out but still picks it up. So I thought I'd move the aerial to point at Rowridge and see if I can get the others. No, all I get from Rowridge is psb1 and 2, no com4, 5 or 6 at all, not even a sniff. I'm totally lost as I'm obviously getting a signal from Rowridge as I can pick up psb1 and 2 with the aerial pointing almost any direction, but I can't even get a weak com4, 5 or 6.

I do have an outdoor aerial on a pole mounted to the chimney also facing Midhurst but I was going to take that down as I'm the highest point on a hill and don't fancy a lightning strike. I've not tried this aerial since swithover. (PO377NX)

Dave Bizzill: Digital UK reckon your best bet for reliable reception of the PSBs is the Luccombe relay, 1.3km to your south. This uses the same channels as Midhurst PSB1, COM5 and COM6, it's basically stomping all over the Midhurst signals. With COM6 still running on low power until after Heathfield switches over, and with the mode changes having increased the margin required, it's not surprising that it no longer works.

Rowridge COMs are on low power, and on their original channels, until Crystal Palace completes switchover. It may be beneficial to change the aerial to vertical polarization [VP], rather than horizontal polarization [HP], as Rowridge COMs will emit more power on VP than on HP after 18 April (they only transmit on HP at the moment). Just rotate it so that the elements run up-and-down rather than side-to-side. Also, you may benefit from using a Group A aerial rather than a wideband - widebands typically have best gain at the top end of the frequency range, actually the part that is no longer used for TV, and an aerial designed to just handle Rowridge frequencies will have more gain than the wideband at those much lower frequencies. *Maybe* you could use a Group K semi-wideband if you're concerned about picking up services that launch in the C31-C38 range in the future - this would have more gain at C21-C28 than the full wideband but less than Group A, for the same size aerial. See Gain (curves), Again and the Group K chart further down the page for a comparison. Your aerial is probably similar to the 'Triboom 46' (a Televes DAT45, I believe).

You will always get better results by putting the aerial outside. The loft has a large number of reflections, which can have the effect of changing polarizations, the roof tiles attenuate the signal somewhat, and the lower height means the aerial may have to see through more obstacles (though that's less of a problem for you as you say you're the highest point around).
