I'm so sorry I didn't see this earlier!! Normally I get a notification but there's nothing in my Inbox. Anyway, the antenna is just a flat antenna that we mount on the window with tape. It's very lightweight and portable with a pretty long cord so it reaches quite a distance. Before we picked up our trailer, I saw it on one of the posts and found it on Amazon. I ordered it and my husband couldn't stop laughing when he saw it. Well, surprise, surprise, on the way home from Chilliwack, we utilized it at almost every stop we made. Even now, with our satellite antenna not getting reception most of the time, we find that we can usually pick up local stations with the Winegard.
I know that it almost seems too simple to work, but it does. I guess people even use it in their homes. Hope this helps and feel free to contact me if you have any other questions. My email is firstname.lastname@example.org.
