Network question. Use coax for ethernet?

[Soundhound]

I heard there's a way to use an existing coaxial cable for an ethernet connection? I have my iMac in our converted garage out back of the main house, and the airport/. internet connection inside the main house. I have them communicate wirelessly now and it's fine, but drops out now and then and I wanted to hook it up by wire.

There's a coax cable laid between the two houses, but no room/facility for adding an ethernet cable, easily anyway. I was told you can get adapaters to use the coax for this purpose. I looked around online and there's a variety of things available, from simple adapaters for $10 or $20, to complex boxes that cost a hundred to several hundred. Anybody know if this is possible, and if it is, what kind of adapter I need?

I've heard decent things about ethernet over coax. Just have to make sure the lines are connected. I've used ethernet over power, and that works pretty well; coax is theoretically the same principle, and I think would if anything have *less* noise issues.

You would use two devices like this one: http://www.netsys-direct.com/proddetail.php?prod=NH-310C&cat=27 one on either end. I'm sure there are cheaper units; that's just the first I found.

Again, cannot stress enough how important it is to make certain the house and garage are connected directly. If they have to go out through the cable box outside to be connected, I would make sure and get a box you can return in case it doesn't work.
