I'd call Wilson at https://www.wilsonamplifiers.com/ to see what they suggest.
I am looking to boost my cell phone signal in a remote area. I have a large hill to the south with an existing 2 way radio tower and electric that I can access. However it is too far to run cable from to an inside amplifier and antenna. I currently have directional on my house and I can access the phone within 4 to 6 feet of the inside cabled antenna but am looking to improve service. Has anyone else ever done this for cellphone service? My carrier is Viearo if that makes any difference!
