As Paul Harvey used to say, "Now the rest of the story".
I tried the tripod mounted DirectTV dish with one of the receivers from home. Didn't work. After lots of internet research and talking with a couple of vendors I leaned that DirectTV is very user un-friendly
to RV'ers. Couldn't make it work, so scrapped the the whole DirectTV idea. Switched to DISH TV, both for home and for use in the Axis. DISH is much more user friendly in RV's, much less complicated and easier to set up and use. Ordered a DISH TV Tailgater antenna and Wally receiver and installed it yesterday. Took a couple of hours, including making a plywood base for the Tailgater that I'll mount on the tripod.
Everything is pretty much plug & play, called DISH for them to activate the Wally and, like magic, within less than 20 min, had satellite TV going in the Axis. With DISH's pay as you go plan, you just activate your RV receiver for 30 day increments, for $7. per mo., and deactivate it when you're not using the RV. So far, I'm a happy camper!
