Model SD9-450 406 - 512 MHz. 9 dBd. Gain 
 

STACKED DIPOLE ARRAY

Design Features: The SD9-450 high performance UHF stacked dipole array is designed for use with highly populated radio sites requiring long haul omni directional coverage. The SD9-450 is heavy duty stacked dipole array features, wide bandwidth, high gain, high power handling capacity, low VSWR, low noise performance and null filling coverage with omni directional characteristics. This stacked dipole array is highly suitable as base station antennas for Repeater and Paging sites.

Constructions: The SD9-450 Stacked Dipole Array consists of eight folded dipoles stacked vertically. This Stacked Dipole Antenna operates at D.C. ground for protection against lightning. N-Female connector of phasing harness cable sealed in heat shrinking tube making stacked dipole antenna waterproofing. The 6 Meters long central mast for mounting the dipoles, shipped in two sections of 3 Meters each.
