I've got a CushCraft D40 rotatable dipole mounted on my tower's mast. At
present, the tower is laying over horizontally. The D40 is about 6' off the

It is resonant at about 7035 with about 220 KHz between 2:1 SWR points. When
I raise the tower to vertical and extend it, thus raising the dipole to
around 66', should the resonant frequency shift upward or downward? Any idea
how far?
