WHAT'S IN THERE?
(And a little on how it works)
The stainless steel whip is mounted on top of a loading coil (under the rubber boot). The
coil consists of copper wire wound around a "grooved" fiberglass rod. Part of the reason
the antenna is guaranteed to work on 40,20,15 and 10m HF bands but not on 12,17 and
30m is that the spacing on the coil is wider at the resonant points on the coil on the
"primary" bands allowing easier tuning.
The loading coil slips into the "body" of the antenna where spring loaded contacts make
the necessary connections. At the base of the coil and rod is a Teflon disk that makes
sliding contact with the inside of the tube and is threaded for the brass "screw" rod that
raises and lowers the coil.
About 7" below the contacts is the motor and clutch assembly (at the middle rubber
cover). Two wires run from the motor to the controller board that is mounted on top of
the base unit.
The base (matching unit) consists of a chromed top cap which includes the mount for the
motor controller board. Below this is a 3" black plastic tube that forms an insulator. At
the bottom is the threaded chromed base cap that is where the SO-239 connector screws
