My Window Unit came with an external antenna port. How do I use it?

Cel-Fi high system gain and sensitivity normally make an external antenna unnecessary (if present it may be left unconnected). However, a system may be configured with an external antenna port for use in situations where no 3G service is available anywhere indoors. Download the Antenna Spec here. PLEASE NOTE: There are no custom ordering options to add this feature through web sales if the Carrier approved configuration does not include the antenna option.

If an external antenna is connected and if the Cel-Fi selects it because a better signal is measured, Cel-Fi's will indicate it is using the external antenna by turning its status LED orange, or by showing the External Antenna icon (depends on the model).
