I thought this this ancient thread died off over 2 months ago.
If your idea works for you then use it.
However I grew up as a teenager in the 50's with the ARRL Handbook and
dimensions were in feet and inches for antenna lengths. Anyone can do the
math in their head for the traditional 5 bands since its all multiples of 8'
for antenna height purposes and it doesnt require a calculator to figure out
15M.
