Actually, the “Internet Prep” is kind of a sales gimmick that’s been going for a few years now.
Your King® Omni antenna antenna is for OTA TV, but King also sells various mobile internet devices that you can add on separately. These devices are not terrible but they are not the best either. King has simply arranged to be featured on various Winnebago RVs (in other words, paid a fee to promote their addon products).
Here’s the thing, mobile internet solutions are dependent on your needs and your budget. There is no one answer for all RVers. I would guess if you ask ten people you’d get ten answers. king is just hoping the Internet Prep sticker will get you to simply buy their products and not shop around.
How do you plan to use internet in your RV? A little or a lot? Do you need it for work on the road? Do you want to stream TV and video on the road? Are you looking to spend as little as possible or is it so vital that your budget is more significant?
Since we don’t know these answers the best thing is for you to do your own research on the topic. It is unlikely that what anyone of us is doing will suit your needs.
The best place to get this information is from the Mobile Internet Resource Center website at
www.rvmobileinternet.com. They don’t sell any products just test and review mobile Internet solutions. The site has massive amounts of the most current information, videos, etc. it’s free to use but only up to a point. For the most in depth info you have to join for a yearly subscription. But even without that it’s a great place to learn the basic of all of this.
I know you want a simple “Do This” answer, but unfortunately it is not a simple subject with a simple answer.
