|DB413 OFFSET PATTERN ANTENNA 12 dB GAIN, 406-512 MHz|
|DB413 uses a 8-stack collinear array
of folded dipole elements to provide 12 dB gain and constant performance over a broad
offset horizontal pattern. Mounts to the top or side of a tower or structure.
Extremely Rugged - Resists winds to 122 mph (196 km/hr)
Broad Response - With 14 to 24 MHz bandwidth, this antenna gives optimum performance in single or multi-frequency systems.
Moisture Resistant - VAPOR-BLOC� cable harness provides weather protection and assures inphase signal distribution to all elements.
Key Applications - Ideal for mobile systems requiring additional gain over a sector or along a coast or area with geographical boundaries.
Sturdy Construction - Mast and elements
are made of high strength aluminum alloys.
Two Piece Mast - For ease of shipment and handling, the mast is made in two sections. A unique center splice assures proper alignment.
Ordering Information - Use model number for correct frequency and specify termination if non-standard. DB365-OS Clamps are included. Order DB5012 Side Mount Kit if needed. Other size clamps can be special ordered. Order jumper cable separately, if desired.
