4G-LTE-ANTM-O-3 AntennaDeciding which antenna to use involves multiple factors, such as coverage area, maximum distance, indoor location, outdoor location, and antenna height. When an antenna is used indoors, the building construction, ceiling height, and internal obstructions must be considered. In outdoor environments, obstructions such as trees, vehicles, buildings, and hills must be considered. Distance is the primary factor when using outdoor-wireless communications. However, coverage area also becomes important when you use wireless client devices to communicate with a wireless device.Features: No tune, multiband coverage, dual 4G LTE, and GPS L1 frequencies.
