Skip, I fought the same situation all winter in Florida. I finally bought the Wilson Trucker antenna on the E place and mounted it to the bus where the old CB antenna was, just high enough to clear the roof and my problems were solved. I did have to hunt a bit for the antenna adapter cable for the phone but Wilson has a page of them which makes it easy. I then got a new (used) aircard for my laptop on the E place, bought another adapter for it and was soon in tall cotton.
Back here in the mountains of NC everything works fine. Total investment less than $100 and all problems solved.
