Help- loadpole.bas
 

I'm trying to decode the math in loadpole.bas (for designing loaded
dipoles) & while some of the formulas are obvious, as a charter member
of the Mathematicaly Declined, I'm getting lost on on most of them
:(.

Heres the section of interest-

Whe

A= dipole lenght (ft)
B= distance from feed point to the loading coil (ft)
D=conductor diameter (in)
F=Freq (mhz)
K=234 (1/4 w/l ???)
Pi=3.14159 yaddayaddayadda
LUH= load coil inductance
XL= load coil reactance

LUH is easy e'nuff.
MC looks like it's the length of the end sections, but so does MH
MA is looking eerily familiar but that "34" is throwing me off, same
for those "24"s in MB & MD.
Maybe its 'cause its 4 in the morning right now but XL is looking more
& more like Black Magic

I might be able to thrash my way through this after a while but this
is more of a "destination" than a "journey" project, so-

Anyone of the Mathamaticly Inclined here feel like trying to explain
to me line by line whats going on here? Feel free to be as pedantic
as you want :).

Thanks,
