7.1.1 Optional Antennas

Where greater range is required, a higher gain antenna can be used. Select a quad band antenna, or one with 850 - 1900 MHz range in North America; a 900 - 1800 MHz range elsewhere. An omni-directional antenna with a dBi level of 5 or more, or directional yogi type antenna, may increase communication range. The antenna must have a SMA connector to link to the STS modem. In order to accommodate an extended antenna cable, the NPT plug on the top of the enclosure will need to be removed (using an Allen Key), and a weathertight fitting threaded in its place.
