[TowerTalk] Tashjain Towers LM470 Remote tower raising control

[Bill Eisinger]

Actually, that just triggered my memory…US Tower sells a remote switch…not sure if/how it would work with the Tashjain system…the US Tower system uses limit switches to stop the motor at max height, etc…but maybe by downloading their tech sheet you could get an idea of how to homebrew something…I would definitely add some kind of limit switch or stop regardless of how you do it.

It's kind of like those ideas about automatically lowering the tower when the wind goes above a certain speed.  It's more complex than one thinks at first.

For this, since you've already got to have power wires and coax going out there, adding a few wires to control some relays seems a fairly simple and robust way.

>> I recently purchased the Tashjain Towers LM470 Crank up tower. The tower comes with an electric motor control onboard for raising and lowering the tower, by a switch at the tower. I need to remote control the tower from in my radio room. There will be a camera to watch the tower raising and lowering. Tashjain does not sell a remote control for towers. Has anyone been able to remote control the LM470 or any of the other Tashjain towers?
