Sat Antenna facts:
There are two primary providers in the US, Dish and Direct
DOMES work with a SINGLE Dish receiver such as a VIP-211 But if you have a multi-channel DVR or multiple receivers and like to watch different shows at the same time DOMES can only see one satellite at a time, this will cause conflicts
DirecTV domes work well but not with DirecHDTV they do not work at all, only SD, and more and more channels are moving to HD only on DirecHDTV so I'd not recommend a dome.
In motion or not? your choice
DISH type antennas.. You get the dish that matches your service,, Dish or Direct, and it works, one receiver, 2,3,4 Multi channel DVR, it works, period So long as it has a view of hte proper ARC of the sky..
I recommend a tripod mounted dish for times when you are parked under the Evil Signal Eating Tree.
