Antenna Connector
The two large cellular antennas are connected to the router using the standard SMA an-
tenna connectors on the front panel. The main cellular antenna connection is labeled
ANT
.
The router cannot operate without a main antenna. The receive diversity antenna connection
is labeled
DIV
or
AUX
for 3G models). This antenna improves the receive sensitivity of the
router and should be used in areas with weak signal strength.
SPECTRE LTE:
There are always connectors ANT and DIV for main and diversity cellular
antenna. The antenna connector in the middle is based on the model number: There is GPS
antenna connector as a standard, WIFI antenna connector (RP-SMA) for Wi-Fi models and
AUX connector (RP-SMA) for SmartMesh IP models.
SPECTRE 3G:
There are always connectors AUX and DIV for main antenna and diversity/GPS
antenna (the GPS mode is chosen internally by activating the GPS User Module in the router).
There can be antenna connector in the middle based on the model number: WIFI antenna
connector (RP-SMA) for Wi-Fi models and another AUX connector (RP-SMA) for SmartMesh
IP models.
SPECTRE RT:
There is not any antenna connector as a standard. Based on the model num-
ber there can be AUX connector (RP-SMA) for SmartMesh IP antenna.
The AUX connector on the Wi-Fi and SmartMesh IP units is a reverse-polarity SMA
connector and should only be used with the smaller Wi-Fi/SmartMesh IP antenna. Do
not attempt to connect the cellular antennas to this connector as it can damage the
connector and the antennas.
The router can not operate without main antenna ANT connected!
Connect the antenna’s SMA connector to the router’s SMA connector. (See figure below).
