4g at last

I went from no signal inside of the house to awsome 4g with a 16db panel sitting on a ladder in the driveway. I was planing on installing it on a 20 ft tv antenna but now I am starting to wonder if just putting it on the eave of the house will be good enough. The signal is at 78% and the cnir is 15. Any thoughts?

Good to hear! If your signal is already good enough at the eaves then you are right you don't necessarily need to mount it on the roof. You could use a wall standoff or a j-pipe or any other such mast.

One advantage of keeping it below the roof line is that you are less prone to a direct lightning strike especially if you already have other elements on the roof that would be more likely arrestors. All the same it is always advisable to add a lightning surge device for any outdoor antennas that are routed indoors.
