Use of External Antennas
S4e UtiliNet equipped meters are manufactured with an internal antenna. However, some meter locations have less
than optimal RF reception. Many meter services are ungrounded. Examples of these types of services include
single-phase form 2S, as well as floating 3-wire delta services, 12S and 45S/5S. To improve the reliability and
safety of these floating services, Landis+Gyr has developed an interface for remotely mounted antennas that
allows RF reception under these service conditions. The High Voltage antenna coupling system protects UtiliNet
components from transients reaching up to 7,000 volts. The Landis+Gyr External Antenna Isolation Solution needs
to be installed in the S4e meter in accordance with Landis+Gyr Specifications. Contact the factory for more
information regarding ordering and installing approved external antenna solutions. See the diagram on the next
page.
