Another thing you might check is birds. On my old aerial rig, a woodpigeon 
landing would send the whole lot into oscillation for about half a minute, not 
doing the already-dodgy signal much good. On my new setup I can still tell when 
a bird lands, I get the odd pixel block (UK DVB-T) but nothing more troubling.

Hmm. 8pm. You got a bird roosting about that time?
