HIGH GAIN AVIATION BAND ANTENNA

Design Features : AC3-127 Omni-directional VHF aviation band antenna is rugged all weather model, radiator enclosed in a ABS radome, uses 6063T6 ultra corrosion resistant architectural aluminum alloy and does not require any field tuning or adjustments. The compact size of omni-directional VHF aviation band antenna allows easy handling, shipping and highly suitable for ATC sites for ground-to-ground and ground-to-air communication without having the requirement of multiple antennas. Antenna termination and feed cable lie enclosed inside the mounting pipe for complete weather protection. All elements are supplied in dismantle condition for easy of shipping and handling and antenna can be assembled in less than 2 minutes. The elements are attached via stainless steel stud systems at points along the antenna skirt hub.

Constructions: The VHF aviation band antenna is consisting of large diameter radiating elements stacked vertically and enclosed in fiber glass tube. The special “Choke and Spark Gap” technique is used for smooth VSWR and constant 3 dBi. gain over the entire 117.975-137 MHz. frequency band. Large diameter vertical radiating element ensures the constant vertical beam-width of 76 degrees over the entire band. The fiberglass enclosure has excellent transparency for RF signals and enough strength to withstand specified wind loads. All exposed metallic parts are supplied with powder coating finish to protect the ATC antenna further from sever environmental condition. The marine grade stainless steel mounting brackets is supplied with the antenna.
