I recently replaced the imitation Winegard bat wing tv antenna mounted on my 2014 210UDS for a Winegard Rayzar Automatic 360 degree scan antenna.

All I can say is WOW, this antenna is the best. In rural campgrounds I pick up 30 and more tv stations.

It was easy to install, blank-off plates were supplied for the old antenna and a blank plate for the hole where the crank was.

I turn it on, push scan and that's it. It finds the direction for the most channels. You push scan again and it goes to the next most channels.
Of course you must also do the search on the tv itself.

I highly recommend this mod.
