I will be doing some cruising in the San Juan Islands of the PNW and I see that there is a company that offers WiFi at many marinas there. It is called BroadbandXpress and has several different price plans. Two questions:Have you used this service and was it good?The web site says you need additional antenna equipment to get a good signal. Is this true and are there lower cost antenna alternatives to what they list?Thanks. Here is the web site:http://bbxpress.net/
