Installation Alternatives Overview
The installation alternatives for the gateway are shown in below sections and
pictures.
Note:
Antennas and equipment must be installed in a location protected from
direct lightning strikes which means it must be installed inside a lightning
protective zone formed of lightning conductors, buildings, antenna tower, and
so on. For more information, see document
Grounding Guidelines for RBS
Sites
, 23/1551-LZA 701 6009, reference [3].
The GNSS active antenna and the RF cable must not be installed close to
lightning conductors, which can carry currents from direct lightning strikes.
The regulatory testing for Gateway 5780 was conducted with the stated
antennas in Table 1 installed and present. To be in compliance with regulatory
requirements Ericsson state that installers and users of this Gateway 5780
must only use antennas of a similar type and with the same or lower gain.
Note that the antenna gain must be configured during installation for correct
maximum output power. See also chapter 7.2.4.
