Linear actuators - Tilt over antenna mount, positioner, etc?

I saw these actuators listed in Northern Tool and thought they looked quite interesting. They are listed in the outdoor equipment section, along side the lawn carts in their master catalog this year.

You could probably use one for a positioner or a fold-over antenna base. At a max load of 1350lbs I would think these would have MORE than enough pressure for any of our applications. Unless you are trying to move a monster dish like KA0Y's or an array like KB8RQ and W5UN have, I think these little actuators would do the trick. If not, get two!
