Arrow,
One of those important things might be to explain to
me how 9 1/2" is a 1/8 wave at what frequency? I thought
we were talking 10 meters...

Hello, Doc
As quoted below 2 meters (146 MHz.)
I use two meters because I have all the numbers in
my head, I don't have to use a calculator.
I don't make 10 meter antennas.

A two meter 5/8 wave length (48") whip does not work
very well. A 3/4 wave length whip will tune
up fine (low SWR) but has a very high angle
of radiation, still does not work well.

Take 1/8 wave (about 9 1/2 inches) of the
3/4 wave and turn it into a coil. And you
end up with an antenna about 48" tall that works
real well. (5/8 wave = 48")
