True Bruce.  Alas, those trees to the West are matched by
trees to the East.  Power lines run in front of the house
to the South.  And the towers, guy wires, and wire antennae
are to the North in the back yard.  It's like looking up
a funnel to see the satellites.

I have another Motorola patch under the roof that also works.
What is the dielectric of wood sheathing and asphalt shingles?
I may try the cake pans on the inside one; not much snow
inside the attic.  :)
