Was about to purchase an aircard router but just stumbled upon the mifi.
Since I'm often in fringe service areas, I use an external antenna and amplifier. Does the MiFi unit have a jack for that purpose?
No. The only connection is for charging or using as a wired cellular modem. However, as the device is wireless you can put it in a location with better reception, up to 50 feet from where you will be using the WiFi signal.
