Is there a way to compute this sort of thing for other antenna/feedline 
combinations ?

For example,  I have a 43 foot monopole with 63 radials, using 45 feet 
of LMR-400 coax transmission line.  Is there a simple formula or 
relationship for this sort of thing ?   Is it just a question of 
feedline length to antenna wavelength or something that counts.  (I am 
presuming, without knowing, that the considerations for a 40 dipole 
might be different from a 43 ground plane antenna.)

Happy Trails.
