RV Television Antenna Options
Our 2012 fiver came with the standard Winegard crank up antenna. At some point I saw where folks were saying good things about the King Jack replacement head and got one. It did improve reception some...

For those who haven't looked at the Winegard SensarPro, it defaults to 10db amplification, but can be pushed to 15db for distant stations. I suspect it would work for the King Jack as well and is much better than the signal meter that comes with the Jack.
As a SensarPro owner myself my understanding is that gain settings run from 0 to 20, with 10 being the default factory setting, which is 0 db gain, 0 db attenuation. Gain can be increased up to + 10 db or attenuated as much as - 10 db from the default setting of 10. If you have documentation stating otherwise I'd be interested in seeing it.
The Sensar IV and King Jack TV antennas are considerably different in that the Sensar IV is unquestionably more sensitive while the Jack offers a wider angle of acceptance. That wider acceptance angle for many people makes the Jack antenna easier to use and leads to the assumption that it's a "better" antenna because under some circumstances it may receive more stations. However, as SCVJeff documented in his tests some time ago using lab grade equipment that perception about the Jack antenna is just that, a perception not supported by actual test results. Regardless, I have no doubt the myth will continue that the Jack TV antenna is "better" than a Sensar IV - the fact this just isn't true notwithstanding. :W
Oh, and FWIW I have also owned a Jack TV antenna but returned to a Sensar IV that feeds a SensarPro ... which is about as good as it's gonna get with a roof mounted RV antenna. ;)
