Signal strength

I have had 2 sky boxes working off the same dish for about two years but
just recently picture breakup has started to occur on both boxes.

Signal strength is more or less steady at about 3/4 bar but signal quality
fluctuates from almost no bar to half.

Where should I start looking to find fault?

LNB, check connections, may need replacing or the dish
may need to be re alligned.

Sky man came to checkmy problem out yesterday. It appears that the
problem is some ****** near me has got a cheap mobile radar detector which
interferes with the sky signal on the low power chanels like BBC1. We reset
the digibox away from RGB to PAL and the problem disapeared.
