I checked my signal right outside the coach then on the inside... Outside I had 4 bars, inside I had one, but if I moved around it was gone. I think it is the coach... I wonder if the previous owner did anyhting that now interfereces with the cell signal...
But either way even if its the provider, I understand that there will be low coverage areas out there, but I just rather not be without a usable signal in case of an emergency.
Thanks for your advice.
What kind of antennas did you use?
