Thanks. I get that. How does it interface to the K3? How does it
back now, and recall some posts about a splitter cable. I'll hit nabble.
> The motor unit has a stepper motor and a roll of beryllium-copper tape with evenly spaced holes (about 0.75 in apart). A sprocket runs the tape in and out in response to pulses from a computer in the shack. The computer keeps track of the tape position and the tape runs up a fiber-glass tube to 1/4 wave length long. You can step it up or down one unit at a time to get the best match with a couple of buttons or push a band button to run to the set position for that band. I don't have a SteppIR vertical, but I do have a 3-element SteppIR beam. The beam has two tapes to make a dipole. The beam has a balun but I would not think you would need a balun for a vertical. There might be some kind of matching, but I can't remember as I have not seen inside a vertical since last field day. The SteppIR products work great, but maybe require a bit more maintenance than an aluminum antenna.
