a television question

All the new HD over the air stations broadcast on what used to be UHF.

That's not the case at all ... while many North American television stations that formerly transmitted on a VHF frequency now do transmit in the UHF band that certainly does not apply to all. Go to the TV Fool Signal Analysis Page (in this case I randomly picked St Louis) and you'll see where some stations formerly transmitting in the VHF band still transmit there - e.g. KOMU-DT, formerly VHF Ch 8, now VHF Ch 8.1. What can be confusing are channels that formerly transmitted on VHF, now transmit on UHF, but still show up on your television as a VHF channel - that's referred to as a virtual channel. As far as your television and you are concerned it's a VHF channel but to your antenna it's a UHF transmission which in turn means whatever antenna you're using must be capable of receiving not just VHF but also UHF channels - ergo, the reason for adding a Wingman to an older Winegad Sensar antenna that was intended originally to be most effective in receiving VHF channels.

You can spend about $20 and add a "Wingman" to you old antenna.

Perhaps, but since the OP has an older 2002 trailer she could also have an earlier version Winegard Sensar II without an amplified head and if that's the case they'd be far better off to replace it with a Winegard Sensar IV which does have an amplified head and comes with the Wingman that improves UHF sensitivity.

To the OP - your first step should be to identify just what antenna system you currently have in order to figure out the most effective solution.
