Where did you get yours JP, I am working on a 20-40 antenna, The diffrence is I don't have any plans. I want mine to have a capacitive top hat for the 40 portion. I wonder where you got your plans,

Another 25 meters of wire is then added to the far end of the coil. I will never run more than 450 watts peak SSB through it. The plan I'm using as a guide calls for 19AWG magnet wire for a coil built on a 1.5 inch form and measuring 110 uH. 76 turns of wire to get there. Now to antenna physics. Does the coil wire at the end of prox.65 feet of antenna really have to be that fat (19AWG). It seems like the current and the voltage would both be pretty low there and a much finer gauge (read less expensive) of wire would probably be okay, but I'm certainly not sure of that. Any thoughts? 73, JP, K5JPP________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list [email protected] http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org Publicly available archives are available here: https://www.mail-archive.com/[email protected]/
