Re: signal loss

Hi Robert,toggle quoted messageShow quoted text
I have seen TV dishes around here flexing so much in the wind that the
opposite sides come within a few inches of each other! This is during the
strong gusts of the mistral (which happens to be blowing as I write). My own
dishes are largely screened from the wind, so I do not suffer from these
problems (the mistral is a W to N wind and I have a nice sheltered spot
facing south for the dishes). I suspect that this is the cause of your
problem. Not much to do but replace the dish with a stiffer one or find a
more sheltered place for it.
Best regards - Alan
