I hear ya on the heat. In the 1 hr I was up there last weekend I downed 2 bottles of H2o. Most of the time was laying the boards to get to end the end of the attic.

Today I drilled thru about 12.5" of stone, concrete, plastic, particle board and wood to get the cable into the room. Very slow going thru the concrete, and couldn't have done it without a 12" 5/8" concrete bit from home depot. Backfilled the holes with backer rod and weatherproofed with external Silicone RTV.

I love Silicone - my dad worked out of the GE Silicone plant in Waterford NY and sold the industrial glues for them. One of his biggest customers many years ago was Rockwell. They had this new space contraption they called the space shuttle. Rockwell bought a 5-part silicone glue from GE to put the tiles on. Remember the problems they were having with the tiles falling off? The first time it was not following the directions to cure each layer of glue in-place. The second time it was a bad batch of the binder (layer 2, I think). Man was it crazy at our house for a month or two. My dad was practically living in Palmdale CA until they got it right. That glue at the time cost about $1500/oz., but could withstand extreme heat, cold, and pressure.

RBeau - great that you already have coax to the attic - that was one of the headaches for me.
