I mounted an 802.11 WiFi antenna and was dismayed to find two drill

There is 'something' as hard as a steel beam one inch under the stucco
near the roofline that just can't be drilled through.

What could possibly be there (in the wall?)?

The reason I ask is I have to replace the flimsy mounting arm with a
stronger one from a Dish TV installation - so I'm going to have the
problem again.

I'll choose a new location - but I don't have much choice within a few
feet given I need line of sight to the WISP access point.

What could it be that is hard as steel one inch below the stucco?

There is no compelling reason to put a satellite dish on the roof. The
difference of twenty feet in 200 miles is undetectable. A better place for
mounting is on a deck. Another good spot is on a fence pole set in concrete.

It has to have a line-of-sight to the satellite, free of trees and all that.
It's often easier to put them on the roof than elsewhere. I agree, though,
it's not a good idea if there is any reasonable alternative.

Having the thing reachable also makes it possible to remove the snow - if
you're in that sort of climate.

Snow? ;-)
