Abstract
A tunable antenna is formed on a boom. First and a second opposed non-conductive support pole extend from a first end of the boom. Third and a fourth opposed non-conductive support pole extending from a second end of the boom. Each pole has a wire guide at its end. First and second spools are mounted near the first end of the boom. Third and fourth spools are mounted near the second end of the boom. First and second wires are spooled on the first and second spools. A third wire is spooled on the third spool and mechanically coupled to the first wire by a non-conductive cord, the first and third wires running through the first and third pole guides. A fourth wire is spooled on the fourth spool and mechanically coupled to the second wire by non-conductive cord, the second and fourth wires running through the second and fourth pole guides.
