Directional Panel Antennas
DB860, DB920, DB930, DB950, DB960, DB970,
and DB980

GENERAL INFORMATION

These antennas generally measure 6.1" (155 mm) in width,
2.8" (71mm) in depth; and range from 12" to 72" (305 to
1,829 mm) in length. Each antenna is supplied with either a
DB390 (Figure 1) or DB390-3 standard mounting kit. The
DB390 kit consists of two identical galvanized pipe clamps
and hardware; whereas, the DB390-3 kit includes a third pipe
clamp and additional hardware for antennas requiring three
brackets. These assembled clamps can be used on round
members measuring 1-1/4 inches (31.8 mm) to 5-1/2 inches
(139.7 mm) O.D. or on angle members measuring up to
2.5" (63.5 mm) on a side.
Optional offset kits (DB391 or DB391-3) are available and
can be ordered separately, providing enhanced cable clear-
ance for antennas that have connectors on the back. Con-
tact an Andrew representative for more information on the
DB391 (Figure 6) or DB391-3 offset kits.
Optional downtilt kits or a wall variable-azimuth kit can also
be ordered separately from Andrew. Downtilt kits designed
for these antennas are the DB5098, a standard downtilt kit,
and DB5099, an extended range downtilt kit. These downtilt
kits include an angle indicator on the lower mounting bracket.
DB5094-AZ, optional wall variable-azimuth kit, offers +45°
to -45° azimuth rotation to minimize clearance from the wall.
DB5094-AZ can be used in conjunction with the DB5098 or
DB5099 downtilt kits.
Detailed installation instructions are supplied with the
DB5098, DB5099, and DB5094-AZ optional kits.
INSTALLATION INSTRUCTIONS
1. Remove the antenna and hardware from the ship-
ping box and inspect it for physical damage.
2. Inspect the antenna feed connector to ensure that it
mates with the transmission line.
3. Check the labels on the back of the antenna and verify
that the frequency range to which the antenna has been
tuned matches the frequency range of the station equip-
ment.
Do not install near power lines. Power lines,
telephone lines, and guy wires look the same.
Assume any wire or line can electrocute you.
The installation, maintenance, or removal of an antenna
requires qualified, experienced personnel. Andrew installation
instructions are written for such installation personnel.
Antenna systems should be inspected once a year by qualified
personnel to verify proper installation, maintenance, and
condition of equipment.
Andrew disclaims any liability or responsibility for the results
of improper or unsafe installation practices.
Do not install on a wet or windy day or when
lightning or thunder is in the area. Do not use
metal ladder.
