Antenna is up and working. Took me and daughter's boyfriend about 3
hours to build and install into attic. It ended up being almost 40
feet long with about 13" spreaders. This works out to be about 8mc. I
think.

For the Balun I wound 4 turns for the coax end and 8 turns for the
antenna end. I put them on a pair of Amidon FT114-67 cores I had.

Al = 5mH/1000t so 25nH/t

Inductance goes as Turns SQUARED. Half the turns, 1/4th the
inductance.

500t = 1.25 mH, etc.
