Paul,
We have direct tv at home, so I just borrow equipment from home and take it on the road. The Genie Mini's work great in tight spaces. I bought a complete HD DirecTV SWM dish kit off ebay for like 180 bucks. Came with everything you need to set it up. The Genie DTV DVR streams like 5 channels at once, so lots of options to record or watch. HD is pretty nice while "glamping" lol.. Anyway if you decide to get DTV let me know and I will send you my account number, saves you and me 10 bucks a month!!
Enjoy,
Jack
