5.7 Acceptable Antenna Configuration
The only acceptable GSM/GPRS antenna configurations are as follows:
1. SSI-SAC-ANKEG-ODG-010 Monopole GPRS Antenna Kit (External Mount).
2. Laird/Antenex pn TRA821/18503P GSM/GPRS Antenna (Meter Panel Mount).
The only acceptable LANOB 900Mhz antenna is the Elster pn 1B12150H01 antenna that comes from the
factory installed on the meter under the meter’s cover.
When using the Mobile Mark RMM-UMB monopole, the ground plate (spider ground) must be used with
the antenna to provide a ground plane for proper operation of the antenna.
If the Antenex pn TRA821/18503P antenna is used, when mounted properly to the meter panel metal
socket, the meter socket provides the ground plane. Additionally, the use of the Antenex TRA821/18503P
requires the installation of bandpass filter PN 1B12483H01 to be installed between the LANOB output and
the LANOB antenna. It will also require the use of an SMA-Male to N-Male adapter to connect the meter’s
SMA pigtail to the antenna.
