Calculating linear load lengths

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?

More elegant and efficient solution is to use loading coil placed abour 2/3 up
the radiator. Best is to use top loading with hat or wire.
