High Gain TETRA Antenna

Design Features: The SD6-400 high performance TETRA band stacked dipole array is designed for use with highly populated radio sites requiring long haul omni directional coverage. The SD6-400 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 maintains constant gain and VSWR over its entire 40 MHz bandwidth, making it highly suitable as base station antennas for TETRA systems, repeater, paging and any other multi-channel communication systems.

Constructions: The SD6-400 stacked dipole array uses 6063T6 ultra corrosion resistant architectural anodized aluminum, consists of Four folded dipoles stacked vertically, fed in phase. The center fed dipole ends and cable connections to the dipoles are sealed in epoxy at the end of the boom for protection against weather and imparting rigidity and strength to the dipole structure. All fasteners are made of stainless steel. This Stacked Dipole Antenna operates at D.C. ground for protection against lightning. The 3 Meters long central mast for mounting the dipoles, shipped in two sections of 1.6 Meters each.

Radiation Pattern: When the FOUR dipoles are arranged 90 degrees apart around the central mast, 6dBd. omni directional radiation pattern results. Aligning the Four dipoles collinearly (facing in one direction) a 9dBd. offset radiation pattern is obtained. The radiation pattern can be changed in the field by use of common hand tools. Vertical stacking distance is factory adjusted for highest efficiency.
