What is VHA?

A Variable Height Antenna is an antenna system designed to adjust its physical elevation or altitude to optimize signal reception and transmission. Unlike fixed-height antennas, which maintain a constant position, variable-height antennas can dynamically change their height based on environmental factors, user requirements, or signal conditions.

By adapting to changes in terrain, obstacles, or signal strength, variable height antennas ensure consistent and reliable communication, making them particularly suitable for applications where maintaining optimal connectivity is essential, such as dispersed security coverage and mobile command and control networks.

DESIGNED FOR RADIOS

Our state-of-the-art tethered drones are designed to augment radio connectivity. With simple and efficient mounts and secure data and power via the tether, our drones are field-proven to deliver network range extension for a wide variety of radio technologies.
