I found a used Pentax surveyors tripod on Ebay $40 shipped.
The cheap ones at Home Depot are ok.
I made an adapter with a 4" X 10" X 1/4" thick piece of aluminum.
Drilled a hole thru the mast mount of the dish, drilled two holes in the plate a little wider than the mast, put a bolt thru the mast then used two J bolts to mount it to the plate. Simple and solid.
Then I set the plate on the tripod and offset it until it was counter balanced and drilled a bigger hole (1/2"?) and put an eyebolt with a nut up thru the tripod hole thru the plate and use wing nut to fasten it.
The eyebolt enables you to bungee the tripod to the ground but I never do as the tripod is so stable it has never blown over.
