Signal Improvement Solutions (Cellular)
AT&T AirCard 779S Hotspot includes an antenna port to attach external cellular antennas. See below for different options for high gain and high performance indoor and outdoor antennas to improve the signal strength and indoor coverage. Additionally, see below for RF bidirectional amplifiers/ distributed antenna systems/ repeaters/ small cells to further improve indoor coverage without directly attaching pigtail/ cable the device.

Pre-Configured Outdoor Cellular Antenna Kits

See below for the most popular LTE antenna kits to boost the signal of your AT&T AirCard 779S Hotspot. If none of these pre-configured kits works for you, see below for manual selection of choice of antenna, cable length, lightning protection, etc.

Cellular Repeaters/ Bi-Directional Amplifiers

Because the AT&T AirCard 779S Hotspot device has an external antenna port you could use the high gain external antenna kits above to boost your signal. However, if your outdoor signal is very weak, or you require a very long cable run to get from the outdoor antenna to the device (long runs lead to large signal loss) consider using an RF bidirectional amplifier/ repeater suitable for the supported bands and cellular operator to boost your indoor coverage:
