Not sure what TVFool is.. I use the Antenna Helper Free app on my phone or antenna web on the computer (Web page)
There is one concern about the Wingman... on some installations there is not enough room to mount it so you have to do things like turn the antenna around to make it fit. Assuming there is enough room.
It just about doubles the "power" of the antenna on UHF, very little effect (if any) on VHF.. The Wieguard Sensar II and III are a bit,,er, anemic on UHF and this corrects that.
YOu may also wish to consider the Sensar Pro as your NEXT upgrade.
