3.8 Grounding
A grounding terminal (hex socket capscrew and washer) is provided on the bottom of the
enclosure for connecting a grounding cable to the enclosure. A 1.5 meter #6 stranded copper
wire terminated with a ring terminal is provided with the RU for linking the enclosure to an
earth ground source.
3.9 Cooling
Passive cooling of the electronic assemblies is provided by conducting excess heat from the
electronic components to the aluminum enclosure. The heat is dissipated to the outside air by
radiation and convection air flow over the enclosure’s external cooling fins. An alarm is
generated if a high temperature condition occurs within the enclosure. If necessary, the RU may
be equipped with solar shields (accessory) that reduce the effect of solar loading on the
aluminum enclosure.
3.10 User Interface
The RU user interface consists of the connectors, grounding lug, and LED that are provided on
the bottom of the RU enclosure. The user interface points for the single-band RU are indicated
in Figure 2-5 and described in Table 2-3. The user interface points for the interim single-band
and the dual-band RU are indicated in Figure 2-6 and described in Table 2-4.
