If you have a Winegard SENSAR II or III (The two antennas we often call a "Batwing") then you really should add the "WINGMAN" for improved UHF performance.
The WINGMAN (which is pictured above) is a 3 element UHF Director array
IT POINTS toward the antenna.
Without it, same position for the batwing
Additional performance improvement can be had by replacing your antenna switch wall plate (inside the RV) with a SENSAR PRO module.. Several advanced features including improved performance. (How I'm watching a Colombo from yesterday Morning as I type).
