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

Remove the antenna and hardware from the ship-

ping box and inspect it for physical damage.

Inspect the antenna feed connector to ensure that it

mates with the transmission line.

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.
