Model AC9-460 450-470 MHz 9 dBi. Gain 
 

TETRA BAND ANTENNA

Design Features: AC9-460 Fiberglass Omni-directional TETRA Band Collinear Antenna is rugged all weather model 6063T6 ultra corrosion resistant architectural aluminum, high class brass alloy and does not require any field tuning or adjustments. All junctions are fully welded to prevent RF inter-modulation and antenna is completely protected within a high-tech ruggedized radome to ensure survivability in the worst environments. The compact size of fiber glass collinear antenna allows easy handling and shipping.

Constructions: The AC9-460 is a center fed design which eliminates the distortion of the radiation pattern and ensures a true omni-directional horizontal pattern. The special stub matching is used for smooth VSWR and constant 9dBi gain over the entire 450-470 MHz TETRA band. The collinear antenna consist of large diameter brass radiating elements stacked vertically, fed in phase and enclosed in fiber glass tube. The antenna termination is enclosed at bottom of the antenna for complete weather protection. The mounting hardware is made of type 316 marine grade stainless steel and supplied with the antenna.
