RTC M2M Installation Manual

EXTERNAL ANTENNA MOUNTING INSTRUCTIONS

NOTE: Limited quantities of the following alternate external antennas are provided with
orders of cell modems from RTC. Additional antennas can be provided, if necessary.
Please call RTC to request (800) 782-8721.

OMNIDIRECTIONAL, TURRET-STYLE ANTENNA

Install and test the signal strength of this antenna just like the "paddle" antenna. If it
returns signal strength -95dB or better (i.e. -90dB), a .75" hole will need to be drilled in
the top of the cabinet to mount the antenna. Select a location on the cabinet that can be
accessed both from the top of the cabinet and from inside the cabinet, preferably to the
left or right (not centered). The top part of the antenna will be mounted on the outside of
the cabinet and held in place by the screw-on nut attached from inside the cabinet. There
is a rubber gasket surrounding the antenna outside the cabinet that will compress and seal
the opening from moisture. Make sure to have a tight seal when installation is complete.
A fine bead of silicon can be used as well, if desired.

YAGI WIDE-BAND DIRECTIONAL ANTENNA

If neither the "paddle" antenna nor the "turret" antenna can gain proper signal strength,
the Yagi antenna is a more powerful alternate antenna. Before mounting, determine the
direction to point the antenna. Point the directional antenna in several directions and
measure the signal using RTC Connect, as described previously. Be aware that metal,
poles, solar panels, and power lines will all negatively affect signal strength. Generally,
a location that is high and away from other solid masses and electrical currents is best.
Knowing the direction of the closest cell tower will also help. There are several third-party
smart-phone apps that can help find this information. After testing, if a signal strength
-95dB or better (i.e. -90dB) is received, a .375" hole will need to be drilled in the cabinet
for the 506473WL15 cable. Use silicon to seal around the cable. The cable should installed
in a manner that limits cable exposure and exposure of the cabinet to water intrusion. The
Yagi antenna will have an installation guide provided. It will include basic hardware and
instruction for adjusting the antenna for maximum performance.
