I believe that the Rowridge (On the Isle of Wight) is the only main transmitter to use dual polarisation to alleviate this problem.
When it was horizontal polarisation only, I used to suffer from this at some time every summer. Touch wood no problems since turning the aerial to vertical.
Analogue was bad enough with severe patterning but digital disappeared completely.
I'm located north of Portsmouth behind Portsdown hill, so the aerial points towards France.
It is strange to see a random selection of horizontal and vertically polarised aerials all pointed in the same direction.
