Model AC-118-137 118-137 MHz 2.15dBi Gain 


Design Features : AC-118-137 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. The complete antenna is sealed inside the ABS enclosure to protect the antenna further from sever environmental condition. Also the antenna is supplied complete in assembled condition to save the assembly time.

Constructions :The VHF omni-directional aviation band antenna is consisting of large diameter radiating elements, enclosed in ABS tube. The special impedance matching technique is used for smooth VSWR and constant 2dBi. gain over the entire 118-137 MHz. frequency band. Large diameter vertical radiating element ensures the constant vertical beam-width of 80 degrees over the entire band. The ABS enclosure has excellent transparency for RF signals and enough strength to withstand specified wind loads. The marine grade stainless steel mounting brackets and fasteners are supplied with the antenna.
