[Elecraft] Trans World Antenna

[Phil Townsend]

Yeah I really like that call AC7AC...

And speaking of room temp super conductors... There some guys up at the lab (Los Alamos) that are getting there.
My old, RIP Elmer W9JWI... Circa 1956 had set up in his shack a super cooled 2 meter antenna.... As the temp dropped he could shorten the elements and shill have the same swr's, watts out.

Sorry for the typos...it a bear typing with an iPad.
