|DB420 BROAD BAND ANTENNA 9.2 or 10.4 dB GAIN, 406-512 MHz|
|With an array of eight dual dipole
elements, DB420 provides high gain and constant performance across a
broad omni or elliptical pattern. Mounts to top or side of a tower or structure.
Rugged - Resists wind to 100 mph (161 km/hr).
Broad Response - With 14 to 24 MHz bandwidth, this antenna gives optimum performance in single or multi-frequency systems.
Resistant - VAPOR-BLOC� cable harness provides weather protection and assures
inphase signal distribution to all elements.
|Frequency Ranges - MHz||A = 406-420 B = 450-470
C = 470-488 D = 488-512
|Bandwidth - MHz
