Model AC12-840 806-870 MHz 12.8 dBi Gain 
 

TETRA BAND ANTENNA

Design Features: AC12-840 Fiberglass Omni-directional High Gain 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. The antenna is supplied in two segments for easy of handling and shipping. The upper and lower portion of antenna is threaded together to prevent RF inter-modulation and antenna is completely protected within a high-tech ruggedized radome to ensure survivability in the worst environments. The antenna termination is enclosed at bottom of the antenna for complete weather protection.

Constructions: The AC12-840 Fiberglass Omni-directional High Gain Tetra Band Collinear Antenna has 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 12dBi gain over the specified frequency band. The collinear antenna consist of large diameter brass radiating elements stacked vertically, fed in phase and enclosed in fiber glass tube. The mounting hardware is made of type 316 marine grade stainless steel and supplied with the antenna. AC12-840 high gain fiber glass collinear antenna is suitable for side mounting on the tower and is supplied with mounting hardware, including a non metallic 1.2 Meters (4 feet) long horizontal arm to hold the fiberglass omni-directional antenna at the top.
