Need Robust Hotspot WiFi Unit (USA)

[WB0VHB]

I've seen the self-contained units like Skyroam but need something with an external antenna option. Looking for a roof mounted antenna for a van with windows only in the front. I can drive by a cell tower and 3 miles down the road drop the connection if another tower isn't available in the direction I'm driving.

You're asking for a cell-phone repeater system for vehicle installations.
