Installing the Wireless Antenna
Before installing the GSM Module into the manhole, install one of
the following antennas:
 Wireless, slim, quad-band antenna (p/n 3800-0162)
 Wireless, mini-wing, quad-band antenna (p/n 3800-0163)
Mini-wing antenna
Install a wireless slim or mini-wing antenna in the road, in dirt, or
under other paving materials in the following way:
Note: While this section describes the process for
installing these antennas, all wireless antennas provided
through IETG also include detailed installation
instructions.
1. Determine the appropriate location in the road near the
manhole to install the antenna:
 Locate the antenna in the road between 457 and 762 mm
(18 and 30 in) from the manhole in which the monitor is
installed. Position the antenna as far as possible from the
massive iron frame and buried flange to prevent shunting
of the RF signal.
 Avoid locations at which cars will remain parked over the
antenna for extended periods (hampering the signal
strength).
 Select a location that drains well so that water will not
collect over the antenna, blocking the signal.
