 Model AC9-150 136 - 174 MHz. 9 dBi. Gain 


Design Features : AC9-150 VHF Fiberglass Omni-directional Collinear Antenna is rugged all weather model uses high class brass and ultra corrosion resistant architectural aluminum 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 AC9-150 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 gain over the specified frequency band. The collinear antennas consist of large diameter brass radiating elements stacked vertically, fed in phase and enclosed in fiber glass tube. AC9-150 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, on the side of antenna tower.
