VEHICLE MOUNT ANTENNA

Design Features: BVM-30-512 Omni-directional VHF vehicular mount 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 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 VHF vehicle mount 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 over the entire 30-512 MHz. frequency band. The UV resistant ABS enclosure has excellent transparency for RF signals and enough strength to withstand specified wind loads. The antenna doesn’t require any ground plane for its operation and is independent from ground. Although a 3m x 3m ground plane is recommended for higher preferences. The compact size of omni-directional VHF antenna allows easy handling, shipping. and highly suitable for vehicular application without having the requirement of multiple antennas.
Mounting: This vehicle mount antenna is supplied with standard NATO 4 holes pattern with biconical spring fitted at the base of antenna for better flexibility. The mounting hardware is made of marine grade stainless steel. Customized mounting arrangements can also be supplied on request.
