Quadrifilars – Helicals
Our quadrifilar and helical antennas are engineered for exceptional performance, delivering circular polarization for applications such as SATCOM, GNSS, telemetry, and space missions.
Quadrifilar designs provide reliable low-gain coverage, while helical antennas are available in both low- and high-gain configurations to meet specific mission needs.
Quadrifilar Antennas
Quadrifilar helix antennas deliver low-gain, hemispherical coverage with excellent circular polarization performance.
They are widely used in GNSS, weather satellites, and other applications requiring consistent performance regardless of orientation.
Our designs can be tailored for specific frequency bands, polarization sense, and environmental requirements, ensuring optimal performance in demanding applications.
Helical Antennas
Helical antennas can be configured for low or high gain depending on application needs.
Normal-mode helices provide omnidirectional coverage and are often used in portable and mobile systems at VHF and UHF.
Axial-mode helices, operating in the endfire direction, deliver higher gain, wide bandwidth, and circular polarization, making them suitable for terrestrial and space applications.
We offer custom helical antennas for search and rescue, SATCOM, navigation, and other specialized uses, optimized for frequency, gain, and polarization requirements.
