Thanks for all the info

I am going to ground out the satellite dish to the tower.

Now it is grounded to my new plazma and I would feel more comfortable
with it grounded to the tower. Don't want nothing happening to that new
plazma. Now of course if it ever got hit by lightning I would imagine
the receiver would get fried, maybe not the tv, the coax goes into the
receiver, then into the yamaha sourround sound then into the tv. A jolt
has to stop somewhere along that line.

I know what an opto-isolator is. (Provides a signal path with a
short-range modulated light beam -- no copper connection) I don't know
if any have been designed/sold for lightning protection.

Anybody?
