VEHICLE MOUNT ANTENNA

Design Features: BVM-118-400 Broadband Omni-directional VHF UHF aviation band antenna is rugged all weather model, enclosed in a ABS radome, uses high class brass and aluminum alloy and does not require any field tuning or adjustments. The compact size of omni-directional antenna allows easy handling, shipping and highly suitable for receiving, transmitting, scanning, monitoring and jamming applications without having the requirement of multiple antennas. The N-Female termination of antenna is fixed at the bottom of the mounting flange for complete weather protection.

Constructions: The VHF UHF aeronautical band omni-directional ground-to-air vehicular antenna is consisting of large diameter radiating elements stacked vertically and enclosed in ABS radome. The special “Choke and Spark Gap” technique is used for smooth VSWR and typical 2dBi gain over the entire 118-400 MHz. frequency band. The UV resistant ABS enclosure has excellent transparency for RF signals and enough strength to withstand specified wind loads. Cylindrical shell/enclosure is used for low wind loading and for minimal effect of ice formation on the antenna operation as well as providing an aesthetically pleasing appearance.

Mounting Option: The VHF UHF aeronautical band omni-directional ground-to-air vehicular antenna can be supplied with standard NATO 4 holes pattern with or without stainless steel spring base. The mounting hardware is made of marine grade stainless steel. Customized mounting arrangements can also be supplied on request.
