$7 each. I gather that we should wind the core with one diameter spacing along the whole length for minimum inductance and maximum Q. The only missing information is wire gauge. Anyone have advise?

Reading the mail, 26 s.w.g. seems to be about average, but it does not seem to be too critical, as lightning is such a powerful signal and the amps have gain to spare.
In fact if we were to forget DXing and think more of the network and distribution, the antennas could be smaller, Quality not Quantity.
Maybe in a perfect system?
my 2 cents.
