[OKDXA] MATH QUESTION

[John Geiger]

Guessing they didn't teach trigonomtry or geometry at
Lillypad High School?

According to the Pythagorean theorem, the antenna
(sloper between A and C) is 128 feet long, correct?

The center point of this would be 64 feet, which
should make a nice 80 meter antenna.  If you run the
coax from the center of the antenna to the center of
the tower (the 60 foot level) then the amount of coax
needed would be 22 feet and 4 inches, more or less.
