Be careful..The primary constants (R,G,L,C) are NOT constant with frequency. 
 Your electrical half wave multiple on one band may NOT be a half wavelength 
multiple on another.

 ----------
If you make your 75 Ohm lines a multiple of  one HALF wavelength on 40M,
the load impedance will be presented back at the input end on 10, 15, 20,
& 40M,
with no need for any transformers since impedances repeat themselves
every
half wavelength in a transmission line.  This works well up to 225 ft.
