If you have the Sensar batwing antenna only and the TV in the TT is digital, you should receive signals, provided your location is close enough to the transmitters of the stations. Also, keep in mind digital signals are exquisitely sensitive to antenna orientation (antenna pointed in the direction of the transmitter). And to some degree, an over the air digital signal can be impacted by heavy precipitation, not unlike a satellite signal is lost or degraded by dense cloud cover and/or rain.
You could add a Wingman antenna (made by Winegard) to the Sensar to improve reception if you have a problem, or replace the antenna with a
Jack Antenna. The Jack is available from a multitude of places online, and can be bought as a replacement head only for the mast mounted Sensar or as a roof mount model that completely replaces the Sensar antenna and mast.
