Carol,
By using the standard formula for a dipole of 468 divided by the freq in mhz,
and using the difference between the 2 frequencies will get you very close.
This is not the correct formula for
an inverted V because that formula will depend on the angle between the two
legs of the V.
However the difference between the two frequencies of either a straight dipole
and an inverted V
will be very small.
For example 468 divided by 3.515 = 133.14 ft. and 468 divided by 3.615 = 129.46
ft.
133.14 -129.46 = 3.68 ft. or about 3 ft. and 8 in. should be added to the total
length.

[TowerTalk] Inverted vee
Hello,
I have an inverted vee up about 100 feet. It resonates at 3615. From past
experience, how much should I add to each leg to get it down to 3515?
Thanks,
Carol
