Winegard makes the
Rayzar Automatic roof mount OTA antenna, but be aware it's not as sensitive as the manually operated Winegard "batwing" amplified Sensar III plus the Wingman add-on or the Sensar IV that includes the Wingman. For even better reception, add the SensarPro inline amplifier that replaces the standard power supply wall plate to both power the rooftop Sensar and enhance the signal with it's own post amplifier. The SensarPro also displays channel signal strengths to make aiming easier. Professional level testing has shown the "batwing" to be the most effective RV OTA antenna currently available.
