Winegard pre-amp question.

Since Winegard seems to think +/- 10 db is sufficient I'd question whether using a preamp with significantly more gain set would achieve the results you're looking for.

Good point. Further research tells me that along with a good antenna, no amplification should be needed if max. 50' of RG-6 is used. Amplification makes up for losses in coax & fittings between antenna and TV and won't make an already weak/bad OTA signal good enough to watch and not pixelate. I really didn't want to have to deal with installing a pre-amp anyway plus more $$

So why do RVs need an amp then? Because of low quality coax and fittings along with inadequate antenna design? The coax leads at the back of a SensarPro are pretty skinny and I wonder what the loss is like in them.
