Using a tripod for setting up a DirecWay dish is not allowed by Hughes. However, lots of Rvers do this anyway. The rules for moving a dish like this are:
The dish must be roof mounted.
The RV must be stabilized
The ladder if accessible, must have a warning sign on it.
THe ladder must be blocked
The dish must be pointed, set up and taken down by a certified installer.

Lots of folks move their dishes without complying with these rules, but these are the rules.
