I have been having difficulty with getting good reception with my verizon air card lately so while at the mini rally PSL, Florida, I asked Wild Bill Miller, an electonics guru what to do. He has been all over the country full timing and and knows the problem with cell service. He had purchased a cell phone booster/repeater from this company and seemed pleased with the results,
Exterior antenna with an inside amplifier.

Bill. please chime in on this and update us with further developments if any.

I also have upgraded my verizon card to the new and improved version with the mini antenna. Dont know if it is any better yet or not as I have not had an opportunity to use it.
