I'm designing and building a horizontal wire receiving dipole and would like some advice on a couple of things that are not clear in my mind.

When constructing the wire elements and using the standard dipole calculations that specify say, 8.03 metres for each leg, is that the length from one end of an insulator to:

a. The centre point of the T centre insulator,or
b. The end point of the T centre insulator, or
c. The actual length of the wire including the turns at each insulator

Currently I have it temporarily set at point B so in effect I have an additional 70-80mm through the insulator and crimped and secured to the main length.

If the consensus is that point B is correct, how much additional wire can be used before the calculated length is affected and resonance lost?

Thanks for any comments in advance.
