Our TV reception went flooey the middle of last week, and we ended up having to get a serviceman (from da big city, 130 miles away) out to analyze the problem.
He was a very nice, accommodating fella and a big help since after much fiddling around, it was suggested a couple of limbs from our twin birch tree might be causing the glitch by blocking the satellite signal to the dish. (So what moved? The satellite or the tree?)
Mr. Repairman helpfully held the ladder steady while Papa Pea climbed nearly to the tippy-top of our extension ladder to do the surgery.
Limbs came down off the tree with no mishap, husband came down off the ladder with no mishap and the repairman went on the rest of his rounds for the day.
