Old Wilson 801201 cell booster

I had the same setup and replaced it with this......4g booster the only difference betwwen the rv model is the rv model comes with an additional 12v cig plug adapter and the refurbished model has the same warranty as new but saves about 130 bucks. I get 1 bar outside and 4-5 inside the trailer and you can be anywhere inside unlike the old wilson unit. This unit has a directional antenna though, you can use an omni directional antenna but with not as much gain, this unit uses std 75 ohm cable like on your tv. I have tried verizon,att and sprint with it and it works well on all of them, there is an app you can download to your phone called "open signal" and it will point you to where the closest cell towers are.
