If you are talking SAT dish...the Batwing TV antenna base will not support the demands of controlling elevation. Plus, I would bet a SAT dish is too heavy to mount on the Sensar's mast.
The simplest rooftop SAT antenna is the Winegard "crank-up" see:
Winegard Crank-Up Satellite TV TV Antennas
These are DirecTV or Dish compliant for 1 bird at a time. And they can cover a Batwing sized hole in your roof. But please notice, they are manual set-up. The RM-DM46 and 61's are optioned with an elevation gauge...gets you halfway to lock.
Best luck
