Jari, what is so special about the bad potentiometer that it defies
substitution?

I have a rotatable tower some 40m away from my ham shack. The old,
faithful tower rotator was hit in lighting and the potentiometer
telling the direction of my antennas was burned. The rotator being an
old, industrial model, the factory told me that there's no such
potentiometers available any more .......
Now ....
Does anybody know, if there are (commercial), potentiometerless
wireless (tower) direction indicators available in the market?
1) With "potentiometerless" I mean, that the direction should come
not from a potentiometer at the base of the tower but with some other
means. Eg. a electronic compass at the end of a one meter stick
assembled horizontally on one of the tower diagonals a couple of
meters above the ground.
2) With "wireless" I mean, that the electronic compass - or whatever
device - should transmit the direction by WLAN from the tower to the
ham shack to a separate display to directly to a computer having WLAN.
I hope I could describe the need good enough. I'm looking for a easy
plug-and-play-system, easy to assemble, easy to use and reliable. And
getting rid of some cables.
There's 230 volts available at the base of the tower.
Any ideas?
Jari, OH2BU
