My Antenna Mart catalog from 1976 lists the SW-9 at $131.50 USD plus $3
for UPS shipping. He mentions a price increase for January, 1977.

Does anyone have anything on this Remote Switch?
For my new tower a guy gave me a control box for and old remote
controlled antenna relay that he once used, but was in his junk box
and so he asked me if I wanted it.
On the back it has a paper stick on tag that says:
Antenna Mart
Box 7 Rippey IA 50235
Model SW9 SERIAL = _________
I searched Antenna Mart using Google and came to a website named
MAX-GAIN SYSTEMS, INC
http://www.mgs4u.com/index.html
So I sent them an email asking them about this remote switch box
They sent me an email back telling me:
>>>
That one is very old, and was made by W0MLY in Iowa, before the company
was sold in about 1990 to Bill Wall, KC4UZ, near Atlanta.
The old switch used a Lucas Ledex stepper motor, and sent pulses to
index it. Position indication was sent back to the control box
by a "coding wafer" which was indexed by the stepper.
Bill Wall completely redesigned it all, and used a totally different
system, with gear-reduction motor drive, no steppers.
We have no data at all on the older W0MLY switch.
