[TowerTalk] Balun For Dipole

[AD5VJ Bob]

I am making a dipole that I am pulling to the top of my tower and am wanting to make my own BALUN for it as well, what size
(diameter/thickness) toroidal core should I buy in order to make a full legal limit BALUN?

I looked in the 2006 handbook, but it didn't really give any specifics on sizes used

I have some 12 AWG insulated wire to use for the windings.
