satellite dish

If that is a pic of the actual dish, those are an aluminum mesh fastened to "aircraft" aluminum ribs. Usually the mesh is fastened with hex head screws or alum. pop rivets. The motors were steel/alum, some had stainless shafts(it's sticking out back). The pipe it's sitting on is probably a 6" double or triple wall steel. The electronic LNA is sitting behind the round cover out front. it is usually cast alum. with a small circuit board and some gold plating inside. That's either an 8 or 10 footer. Hope this helps some,,
Used to install them back around the '80's.
To add to my post a little more; the cables going into the house will be good copper in the coaxes and either a 6 or 8 wire cable going to the motor.
