RF-7000E Operations Manual

Pre-Installation Site Review
Each site should be thoroughly reviewed before any equipment is mounted. Site review should
include, but not necessarily be limited to, the following factors:
Weather
Determine whether environmental conditions necessitate special shielding of the repeater or
other equipment.
Security
Determine whether some type of barrier is needed to protect equipment and if a security light is
required.
Aviation
Review tower heights and obstruction lighting requirements as specified by the national aviation
authority, e.g. US-FAA, US Federal Aviation Administration or Transport Canada. Normally
towers 200 Ft AGL and taller require obstruction lighting. Towers closer to airports have
additional lighting and marking requirements. File NOTAMS as required during construction.
Optional Site Equipment
Determine whether additional site equipment, such as a convenience power outlet, pump,
generator, or light is required, and, if so, where equipment is to be located and whether special
enclosures for any equipment is required.
Wiring and Wiring Access
Determine any special wiring requirements.
Cabinet Access
Determine whether there is enough room for the repeater door to open, once mounted.
The RF-7000E assembly can be mounted on a steel tower, on a steel pipe or square-rail frame, or on
a wall. The length of all power leads should be limited and the wire size adequate to minimize the
voltage drop. The repeater assembly, battery boxes, solar panels, and antennas should all be
mounted before any wiring is done. Mounting-hole dimensions for the repeater enclosure are shown
in Figure 21.
Prior to cutting to length and connecting the waveguide feedlines, verify which repeater
’s receive
frequency associates with each antenna port and associated terminal radio site. The repeater
receiving frequencies and transmitting frequencies are marked on the top of repeater, near
waveguide antenna ports. Coordinate site names are marked in the same location, when known.
The waveguide feedlines are terminated in CPR112G, Waveguide Flange. The repeater is not
designed for pressurization. Use external pressure windows at the CPR112G, Waveguide Flanges if
the feedlines are to be pressured or dehydrated.
CAUTION:
In an extremely hot and sunny environment, such as a desert, shading from direct
sunlight may be necessary to prevent the repeater and associated equipment from
overheating. Locating battery enclosures in the shade of the solar array is
recommended.
