It looks like a recycled Winegard HF-FV45, a short-lived model from a few years ago that, IIRC, only Solid Signal was selling back when they were still tight with Winegard (via www.winegarddirect.com, a Solid Signal operation)
Was looking at antennas for some family and friends that found out I've cut the cord and asked for advise but don't want to go the DIY route like I did.
Don't want to recommend one that I can't find any gain values or such on. That PDF did say it had a 30 degree beam width in a round about sort of way.
