I need to see if Verizon offers a MiFi unit that accepts an external antenna. I live on a boat in the San Leandro Marina of Northern California. Verizon knows this location to be a cell black hole. Local entertainment is provided by nearby hotel guests screaming into their cell phones while standing out on their room's balconies. I get barely acceptable phone performance but find that my MiFi-2200 rarely works at this location. I had a 3G wireless solution before that accepted an external antenna. But after Verizon assured me my MiFi2200 would solve the problem, I caved and got it. It works anywhere else in San Francisco Bay and offshore, but not in my home berth! I've heard that the MiFi4510L accepts an external antenna and would consider that unit. However Verizon disowns any such model on their web-site and recommends I pay for the latest, greatest and most expensive, without indicating if any current MiFi units accept an external antenna. Does anyone in Forum land have a solution?
