According to ON4UN - linear loading can be made virtually loss free (pg
9-39). Can't do that with coils.

He suggests making the linear load stub 30% longer than the missing portion
of 1/2 wavelength. (page 8-13) Then trim and try.

Does anyone have a good source for calculating the length of linear loads
for a shortened 40 meter Vertical? I'm experimenting with a 20' vertical
and a pair of 10' parallel lines moved the resonant point near the 7 Mhz
band. Any suggestions?
