Cell phone signal booster. Anyone have one?

Background.

I live out in the country and for the past 6 months have experienced many dropped cell phone calls. I put on a metal roof a year ago this month and didn't start to notice drops until about December. I upgraded our phones in January but still have the problem. I live on a high hill within 3 miles of the interstate and have an unobstructed line of sight with two cell towers. I'm a Verizon customer and don't know if their signal goes through them or not. Our phones fluctuate between 1-2 bars 3G-4G, both inside and out. I'm pretty cell phone illiterate so now I'm rambling. The funny thing is I sometimes use my cell phone as a hot spot when my satellite internet is down and it never fails. I'm only interested in dropped calls, not boosting my cell phone data speed.

Up to this point Verizon support hasn't offered much of a solution other than trying to sell me their signal booster. Problem is it uses an internet connection and since my internet is satellite they can't guarantee it will work. There are other options out there that use an outside antenna to work with the cell towers.

I'm curious to know if anyone else has something implemented that will solve my problem.
