Apparently there is already electric outlets available up there.

And as for signal, we have yet to even pick out a projector.

I wouldn't recommend a mototized mount unless you need to get the projector out of the way. One less thing to maintain.

Since you say that you don't have a projector yet, does that mean you haven't picked out a screen? As stated previously, that can greatly affect your choice of projector.

As for a projector, I recommend going with DLP since it has a sealed light engine (dust is your enemy). Though it is probably outside your budget, Panasonic makes some nice projectors that have this nifty self cleaning filter (won't do well in situations with fog/haze, just good for dust).

As for the electricity already being there, just make sure it's clean power. The other issue you may run into is if your source is not sharing a ground with your projector you may get hum bars (which can be eliminated, just something to think about).

I seriously would suggest a professional installer to help you they would have the experience to calculate throw distances to choose the right projector, and mounting distance, and the right cable options.

However if you really want to diy it here are some things to consider.

Mount companies offer options that allow you to use any standard metal pip to custom cut the height off the roof. The mount attaches to the pipe by being threaded around, like a coupling. This is not subjected for an active gym where flying balls could knock the projector out of alignment.

Another option would be to mount the projector on an opposite wall, which is what I suggest for gyms. By using the right lens choice for your projector you can achieve some super long throw distances. You might also consider directly mounting the projector to the ceiling and key stoning the image to reduce cost, and keep the projector height off the ground to avoid balls.

as far as cabling, I would sudgest using the bulans if you’re going over 150', however composite, component and vga I have been able to achieve good quality picture on high quality cables over distances of 300' however that’s pushing it.

I would suggest cat5 for control, or an ir blaster.
