Hi Adam,

This is still a work in progress, the transformer simply will bolt in the transformer case (typical nema). The top is big enough to bolt the choke and actuator underneath it.

You shouldn't need a long throw actuator (s) for the 30gig band is just right. I found a new surplus one on Ebay. There are lots of them there cheap. Simply use a rocker switch to extend and retract the actuator which would be bolted by the pull handle or the handle removed.

It's simple enough to work good! 

The nice thing is this will be weather proof since I am running out of room for stuff that isn't.

Regards,
Jim Mora

Do you have any pictures of your slide choke/satelite
dish actuator? I've been trying to decide how to
remotely control my two slide chokes, and hadn't
considered an actuator. I used to have a 7' dish so I
know exactly what you're talking about.

thanks
Adam
