Davis WindTrak AV Antenna Mount Wind Vane

The Davis WindTrak AV Antenna Mount Wind Vane (Model 3160) is a precision wind direction indicator engineered for mounting on whip antennas up to 1/8 inch in diameter. Built around a sapphire jewel suspension bearing, this wind vane delivers accurate wind direction readouts with minimal friction and exceptional reliability in field conditions where traditional mechanical wind indicators would drift or stick. The design combines a large fin-to-inertia ratio with an adjustable tacking tab system, allowing operators to calibrate wind direction readings for specific antenna installations and environmental conditions.

The sapphire bearing is the critical mechanical advantage here—it eliminates friction points that cause lag and dead zones in less sophisticated designs. The large vane geometry means the indicator responds quickly to actual wind shifts rather than buffeting or transient gusts, providing stable directional information. The adjustable tacking tab allows users to compensate for mounting angle variations and antenna-specific flow disturbances, ensuring true wind direction is represented across different installation scenarios. Weighing just 0.5 pounds and measuring 18 inches in height, the WindTrak AV integrates into existing antenna systems without adding significant weight or wind loading to the mast.

This mount is suited for communications operators, meteorological monitoring, maritime applications, and fixed-site antenna systems where wind direction data informs signal propagation, antenna orientation, or environmental assessment. The compatibility with Metz, Shakespeare, and standard whip antennas means integration into existing tower and mast infrastructure requires minimal modification. Multiple units can be combined on a single mast to support redundant directional monitoring or multi-frequency antenna arrays, making it a scalable solution for complex RF environments.

Davis Instruments positions the WindTrak line as a value-class wind direction solution, delivering lab-grade bearing reliability at a fraction of aerospace-grade indicator pricing. For stationary and semi-permanent installations where durability and accuracy matter but full-scale meteorological stations are unnecessary, the WindTrak AV represents a cost-effective baseline for wind telemetry.
