 JE> Where did you arrive at the value of 2808?
468\2*12. The 468 gets 1/2 wave results in feet. The \2 gets 1/4 wave
results, also in feet. The *12 turns it into inches.

Here he screwed up. He said radials are 5% longer (he is right on that,
BTW). 2808*1.05 = 2948.4, which is the correct answer for the proper
factor. Probably a slip-of-the-calculator finger error, you think? I can
remember taking a course in operating a slide rule in first-year
engineering college. The prof had a BIG slide rule on the wall to
demonstrate with. About 10 feet long. He was demonstrating how to
multiply 2*4 and announced that the answer was 3.98. Close enough...
Ya gotta be careful with those fingers!
... Operator, give me the number for 911.
