Well, I checked out the Sensar Pro at the Wineguard web site. There are manuals in PDF so I looked them over and as someone mentioned the Sensar Pro goes inline with the antenna before the switch box. I suppose that BOTH the switchbox booster and the Sensar Pro can be turned on at the same time. It is ten dollars less through the Winegard site over Camping world.
I understand about the wingman attachment but as I understand it the attachment should not be necessary.
Thank you all for your assistance. Maybe I will look around and see if I can find the Sensar Pro elsewhere for even less money!
