[Drake] Remote ant. sw

[Telegrapher at att.net]

i have come across a 5 position remote antenna switch that sure looks like one i had back in the 70's.  However not paperwork and it came with a homebrew control unit.  What i'd like to know is what kind of voltage came from the control unit to activate the switch in the remote antenna box.  No markings whatsoever and the control box only puts out about 16-20 VAC, clearly not what it takes to run the remote unit.  I don't think.  At least it didn't when i tried it. surely they wouldn't run 110V up that line, maybe 48 or so?  Help.
