When I bought my RV it had a Winegard Batwing that was not working, I cleaned up all connections and tested to see if it was broken, it was,so I replaced it with a new bat wing then ran a Channel Scan I was not impressed with the amount of channels that I got. This was done in my driveway here in the south bay of So Calif about 30 miles from the transmitters, using my SensarPro.
I then went out and got a Wingman add on, that put my channel scan up to 47,but I had a clearance problem with the Wingman
So I opted to put a Jack on and my channel scan went up to 85
The debate will go on and on, but I know what works best for me,in the real world.
