Sierra Wireless Aircard 803S/ 4G LTE Tri-Fi Hotspot Antenna

I would like to know if you carry an antenna for the Sierra 803S, compatible for both ports. The antenna would be an indoor, something that would boost the signal for the Sierra 803S

There are several antennas to choose from. For example: https://www.rfwel.com/shop/3G-4G-Mul...y-Antenna.html is the recommended indoor/outdoor antenna because if offers MIMO capability. You could also get a single or two individual antennas such as: http://www.rfwel.com/shop/Cellular-P...t-Antenna.html or http://www.rfwel.com/shop/Cellular-P...e-Antenna.html. The adapter you would need for this is: http://www.rfwel.com/shop/aircard_80...a_adapter.html.

One important thing to note, however, is that indoor antennas tend to be low gain. So unless you are placing the antenna in an area of the room that already has a strong signal (and running cable to the 803s in an area with a weak signal) you will not see much improvement from these indoor antennas.
