Purchasing a portable satellite antenna, which one????

OK, I just went through this same process for a permanent mount auto dish on the roof, for when there is a clear view of the southern sky. We have a Winegard Carryout that has a separate power supply. Unless we got a carryout or carryout G2, we would have to reconfigure the receiver each time we switched for the roof mount, to the portable one. Their are many auto locate dishes that are much cheaper than the G2, but the G2 uses the same receiver setup and has a larger dish reflector, and less susceptible to rain fade. Both of the carryout's can only receive one sat at a time, which is not a problem if you are using a single tuner receiver, without any DVR capability. When/if you have a DVR function, the dish will switch sats, when the recording process is active, and on a different sat from what you are currently viewing. I though about getting a traveler to access all available sats at once, but unless you have a high end DVR, it would be a waste, so we decided to go with the G2 for a permanent mount. Yes, we do need to change inputs when we change from roof to carryout.
