Well as it turns out there are many ways to get TV that do not involve replacing the Batwing. Some might even be better than batwing (But a lot more work)
You can still buy good old fashion TV antennas designed for outdoor tower mounting, In fact I think Wiegard makes one or two or twenty.

The flag pole site also sells a 12 volt operated rotor.
The problem with these antennas is they are BIG, you need to fold them back up for transport.. I have done this with House type antennas but it's not an easy job.
