I used one of these Winegard RD9046 Portable 18 Inch Satellite Dish Antenna when I was bringing along my SAT RCVR items a few years back...

I could wind up all of the RG cables i was using around the base and also could hookup my dish pointer meter on the platform.
I always set mine on the hard bed cover of my truck so that I would stow it away when I left the area. These kind of things might wander off on you if no one is around..
When I did this it was only SD SAT TV so I used a two port DISH HEAD and run one RG cable to the living room area and the other RG cable to the bedroom area. Then hookup to my two SAt RCVRs I would bring along from my DIRECTV home account.
Did this for a few years until the National Broadcast came out with their digital HHDTV signals. Now we pick up digital HDTV signals from the local towns for free with ease using the BATWING TV Antenna. Don't bring along the SAT T items anymore...
