I had to get a 3 bar signal for it to work

3-4 bars and transmission and download speed is great

Adjusting it for the right angle to get the maximum signal took a little bit of ladder time, but we were able to get three bars from zero inside and decent 4G data service once installed.

However as soon as I make a phone call it loses ALL bars of service and drops the call instantly

We boost works great went from 0 to 1 bar inside to 4 bars now .

It's boosted my bars from 0-2 to a rather study 2, occasional 3.

I went from a weak 1 to 2 bar signal indoors that resulted in constant buffering, dropped connections, or failure to connect in the first place to 3 to sometimes 5 bars without most of the issues mentioned previously
