I have the Winegard portable tripod and I've been using it for well over two years with good success. Those of us with the talent can sometimes site the dish and hit a bird on the first try BUT it's not that easy.
I've done it a couple of times using only a compass and a level on the base of the tripod. Sometimes I need to use a claw hammer to make shallow divots for the leg so the mast will stand vertical.
I use 3 bungee type cords (short ones with the attached plastic ball) and stakes to pin the tripod to the ground. If I'm on asphalt I'll use 4 gallon sized milk bottles. That's 33+ pounds or so and that holds the dish quite well. The TPod comes with a center bungee and a screw in type stake. Lost the stake inside the first year.
I also use press on RG-6 connectors which I got at Radio Shack so I don't have to screw on a connector. "Hackbar Steve", Jestme13 gave me an 8" flat coax coupling that I use on my door sill. Work great!
Once I had the dish set in and banging a 90% or better signal I took a magic marker and drew a line on each side of the LNB so I don't have to waste time guessing the angle or position.
I leave all me setting knobs on a light drag and I'll site the dish in within a few minutes without a squawker. Just turn up the volume on the TV if you're close to the rig or have a person inside the MH call out the percentages. Anything over 70% will work.
When I take the dish down I remove the LNB and loosen the knobs until I can fold the TPod down as flat as possible.

Throw away the base that comes with the dish and place the dish on the TPod.
