Hi Warren,
We have a VuQube that we use with our RV. As Roger said, it won't work at anchor, 'cause any movement will cause a loss of signal. However, it could work if you put it on a dock, and have a clear view to the south (depending on your location).
We really like the VuQube. It is, indeed, a dish in a box... with the RV, Joan generally has the satellite signal within a couple minutes (she sets that up while I'm doing the other utilities). We have had an automatic system on our coach before, and this is actually faster to acquire the signal. If you happen to be parked under trees, you can run the coax to an open view of the sky. Compared to a dish on a tripod, this is a piece of cake, since you can make all your adjustments from inside the RV with the remote. We are sitting in Phoenix right now, watching Dish via the VuQube. When we were in Yellowstone, it was the only way to get TV.
The downside: you have to put it somewhere when you're cruising... it takes up about 18" cubed space. Not a problem in the RV, but that's some valuable real estate in the C-Dory. Also, since it is portable, it can be moved... or swiped. Without the remote, it is useless, but not everyone would know that.
Simple set up: put the carrying handle facing north and plug in the coax. No need for a power cord, it gets power through the coax. Step inside, turn on the satellite receiver and TV. You get a chart for elevation and azimuth - use the remote to set the dish, then fine tune. After doing it a time or two, it rarely takes more than a couple minutes (our automatic system in our coach would sometimes take up to 20 minutes).
It is MUCH less expensive than the automatic systems and does have the advantage of being able to be moved from rig to rig. For the price ($699), I think it's a good value. You see a lot of truckers using this in their cabs, usually mounted on the back.
So there's no confusion, it is NOT an in-motion system. You have to be parked (not moving at all) for this to work. For what it is, we are very pleased with ours.
Hope that helps.
Best wishes,
Jim
