Welcome to the forum. I bought the Wilson system specifically for my two month trip last summer. Overall I think it works real well. I have a Verizon Palm Treo which doesn't seem to have the best reception by itself. While on the road in 10 western states and in British Columbia Canada the Wilson system did seem to really boost weak signals. I bought the hard wired system becuase from my research it seemed to work better than the wireless system. Often I would have a weak signal fading in and out on the phone by itself. When I plugged in the amplifier it would boost it up to several bars. It will not work however when there is absolutely no signal.
I was able to get a signal from Victoria Canada which I assume was from a US tower in Port Angeles WA, but it could have been a tower in Canada-not really sure but the phone did work.
Also I bought the connector for my Verizon wireless internet card. You need to make sure your PCMCIA card has the jack for an external connector. My newer card that Verizon gave me did not have the jack so luckily I found an older Kyocera 650 which has the jack. I think it is actually a slower card but it works with the Wilson connector and it seems to be fast enough for me.
I bougt Model#811201 and the small magnetic antenna. I put the antenna wire under the door moulding and half way through my trip, the opening and closing of the door cut the wire. I was able to tape it back together but it came apart. just recently I will likely buy a new antenna and then drill a hole in the roof, maybe getting one of their larger trucker size antennas.
Hope this helps.
