General
Typically, the internal antenna used with the ILC/ILN option board is sufficient for reliable communication with the
EnergyAxis network. However, if the A3 ALPHA meter is enclosed in a metal service cabinet or the antenna needs to
be mounted higher to increase communication distances, an external antenna may be used.
This leaflet contains general information for installing the A3 ALPHA meter equipped with connections for an external
antenna.

TRAB9023P and TRAB9023NP, respectively. The version with an "N" does not require it to be mounted on a ground
plane and should only be used in non-metal cabinets. The version without an "N" requires a conductive ground plane
under the antenna and should only be used in metal service cabinets and meter sockets.
