Helical Antennas

Circular. Directional. Compact. Rugged.

AntennaTec helical antennas are available in standard and custom configurations for applications requiring circular polarisation, directional coverage and reliable RF performance.

Helical antennas are widely used in UAV links, satellite communication, GNSS-related systems, telemetry, jamming systems, counter-UAS platforms, tracking, monitoring and specialist RF applications.

The range can include single-band, dual-band, wideband and high-gain helical antennas, with suitable radome, connector, mounting and platform-integration options.

Custom helical antennas can be produced to meet specific requirements for frequency range, gain, polarisation, beamwidth, mechanical size and deployment environment.
