Each is made by the members of the W5ES Amateur Radio Club. Each is handcrafted as if we were making it for ourselves.
The ElectraSlide Antenna is a modification of the DK3 design by Don Johnson, W6AAQ. There are no voltage dropping resisters to heat up. It operates on the full 12 volts.
The control switch and the matching toroid are supplied. - - All you need is a standard 3/8 by 24 thread ballmount, 2 wire sheilded microphone cable for control wiring, and a CB whip cut to resonance.

Operation and construction.
By their name you should know that screwdriver antennas are operated by a cordless screwdrive. A coil form is mounted inside a tube and is extended or retracted by a cordless screwdriver. The coil is long enough to allow the antenna, resonant on 10M with it retracted, to be extended to cover all frequencies down to below 75/80M, including MARS.
As the antenna extends it becomes center-loaded and resonant on any given frequency. The ElectraSlide Antenna has a 12 volt motor controlled by a momentary (on)off(on) switch (supplied) via your shielded two conductor cable.
The coil form, wrapped with #16 tinned copper wire is made from 1-1/2 inch UV resistant PVC pipe which has a machined cap press fit on it. The cap is threaded to accept a 3/8-24 whip. The base, a machined plug, fits into the tube and has a 3/8-24 stud to fit into a standard ballmount. The tube is made from two inch thin wall pipe, 32 inches in length.
