Place the antenna perpendicular to the ground, either right
side up or upside down. Do not mount the antenna
horizontally.
Always use an antenna mounting bracket. Do not mount the
antenna such that it is in contact with another object, as this
may interfere with cellular reception and transmission.
Measure Received Signal Strength (RSSI) for Best Antenna
Placement
Measure the received signal strength by pressing the RSSI button. This
switches the LEDs to signal strength mode. Now, slowly move the unit
or remote antenna to achieve maximum signal strength. Pick the place
where the most LEDs (up to four) are lighted.

If you cannot obtain a signal strength reading of 2½ (TWO LEDS ON
SOLID AND THE THIRD LED ON SLOW FLASH), you will probably need
to move the unit and/or remote antenna higher, or switch to a special
antenna as described below.
