I think you will get your wish.
how to set up a tv at a tailgate?
Along these lines...does anyone know how to hook up a second battery and easily run your car's stereo system off it during tailgating?
Depending on your vehicle I have always found bringing a small generator along is the best option. They are reliable, and are easier to set up than anything else I have looked into. Usually you can find a "cheaper" on on sale if you do it before tailgate season, and can fit in the back of a SUV or Pickup.
We use a 2000 watt generator and that works very well for our TV, stereo, crock pot, charging cell phones, etc. Pretty much handles everything.
Are you going HD dish or just regular? The HD dish is a bit harder to align - you need to find 3 angles to get it perfectly, tilt, elevation and azimuth. I found a great $200 stand that works perfectly for my direct TV HD dish. I get it set up in minutes at every tailgate (as I live in Chicago and go to all games) so I am always re-setting all three. I would check out this website and order this stand: http://delsand.com/. If you are going from game to game (or even a different parking spot each game), you will want to eliminate the head aches.
Come find us in the Blue Lot if you want to see this in action (UM Flag, City of Chicago Flag, State of Hawaii Flag).
Where do you put it? Isnt it loud?
Generator + dish :)
Here is what we did for the past 3 seasons:
2 Marine batteries linked together with an inverter hooked up. This powered a 26" tv & the satellite box/dish for around 12 hours. We didn't allow anything else to be plugged into the inverter. It was a great set up and then we charged them after each use.
This year we are going to a generator due to people wanting to plug in music and other cooking devices. But the 2 marine batteries worked great and was quiet. If you go this route and you want to use a larger TV maybe linking up 3 batteries might last longer. Our buddy that figured all this out is an engineer and he did the math on everything to know what we could use for how long.
Get some thick foamboard insulation and build a "box" for it, with proper vent holes and so on. Will cut WAY down on the noise.
Some big ass batteries and an inverter should be all you'll need. Or, as others have said, a generator.
the advantage of using the batteries is that you potentially recharge them with the alternator in your car. You'd have to know what you're doing though.
Anyone have a good technique for dish pointing? I have a heck of a time trying to get it zeroed in when I parked at AAGOC last year. I only was successful one time (little bro game). I've tried using the dish pointer app as well as the compass to no avail.
