Model BVM-225-400 225 - 400 MHz 2.5 dBi Gain 
 

VEHICLE MOUNT ANTENNA

Design Features: BVM-225-400 Omni-directional UHF ground to air 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 (0.9Meter shipping length) of omni-directional UHF ground to air antenna allows easy handling, shipping and highly suitable for vehicular application 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. 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.

Constructions: The UHF ground to air aviation band 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 constant 3dBi. gain over the entire 225-400 MHz. frequency band. The UV resistant ABS enclosure has excellent transparency for RF signals and enough strength to withstand specified wind loads.

Mounting Options: This vehicle mount 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.
