2.1.4.2 Antenna Mounting Instruction
For best reception: connect the antenna directly to the rear of the meter, if the
meter is not installed in a metal panel or enclosure.
If the rear of the meter is behind a metal panel or in a cabinet, use a coaxial
cable to position the antenna outside of the enclosure in the open air.
Use the shortest cable that can reach a suitable location. The antenna on this
Meter and any End Devices should be installed in a vertical position, pointing
towards the sky.
Metallic structure should be kept at least 0.8" (2 cm), although 2.4" (6 cm)
is recommended away from the antenna.
Any casing that encloses the antenna should be plastic. In addition, it is
also wise to avoid plastic case with dark fillers or colorants.
Refer to Section 5 for more Environmental / Operating Conditions.
