Chapter 2 • Functional Description
Position of the ORION
®
and/or EMTR-3
These are important factors in RF deployment. The ORION
®
antenna is
omni-directional. The signal radiates 360 degrees. The EMTR-3 antenna
alignment is parallel to the front cover of the electric meter, and is the most
sensitive RF reception surface.
Face the front of the meter/EMTR-3 toward the ORION
®
transmitter when
possible; even on opposite sides of a building. This allows maximum
communication surface and distance between the units. Allow for some
additional power margin in the signal strength to accommodate seasonal or
other changes in environmental conditions.
In the future, after installation, the site owner should inform you of any alterations
to the site that could affect radio performance.
