We use the BATWING antenna here on pole outside our OFF-ROAD POPUP trailer.
This is the BATWING that has the dipoles on it. I installed one of the Winegard Antenna Wall Plates that has the power supply built-in.
We have this connected to a VIZIO 22-inch flat screen HDTV set.
We point the BATWING towards the local town transmitting the NATL BROADCAST TV signals.
We just go to the TV menu and select ANTENNA and then run a scan. We usually see 6-36 digital stations here on the TV just about every where we go heree on the East side of the US...
All transmitted in high def HDTV mode on our 22-inch TV.
One trick we learned here is if when scanning we don't see anything being logged into the scan window with more than 30% scan then will stop scanning and move antenna a few degrees one way or the other and start the scan again.
My BATWING antenna has a small LED ON and the Antenna Panel halso has a lit LED ON when the button is pushed. This tells me 12VDC is being fed to the antenna to power up its internal PRE-AMP inside the BATWING.
My BATWING looks like this one except it is mounted on a attached pole on the side of my POPUP. I reach out the window flap to rotate it...
Works good for us....
