After some serious gusts this afternoon, my Hummy is no longer receiving any Five related channels, giving me a bad or no signal error. Signal status is reading a very low strength with little or no quality. E4+1 is reading similar - and Sky News is unwatchable.

Anyone else having this problem, or has my roof top aerial been knocked out of alignment?

Works all right for me. That's several different multiplexes, so if the problem persists, I think it could be your aerial.
