Product Overview
A full-band antenna for professional GNSS positioning workflows.
ZENITH is Kalmix’s full-band GNSS surveying antenna for professional positioning workflows, including RTK rover setups, base stations, monitoring installations, and precision field systems.
It is designed for multi-frequency, multi-constellation reception across GPS, BeiDou, GLONASS, Galileo, and L-Band correction services. The antenna focuses on phase stability, outdoor durability, and consistent signal reception in demanding positioning environments.
ZENITH is not a GNSS receiver by itself. It is an active surveying antenna intended to work with compatible RTK, monitoring, and survey-grade receiver systems.
Survey-Grade Capabilities
What separates a survey-grade antenna from a standard GNSS patch.
Five antenna characteristics that matter in demanding RTK, monitoring, reference station, and PPP positioning workflows.
±2 mm
Phase center stability
Stable phase center behavior helps maintain consistent measurements in survey, reference station, and structural monitoring applications.
Wide-beam tracking
Low-elevation satellite reception
Broad sky coverage helps track satellites at lower elevation angles, improving geometry and availability in partially obstructed environments.
Filtering
Out-of-band interference rejection
Built for urban, industrial, and field deployments where nearby RF sources can degrade GNSS receiver stability.
L-Band ready
PPP correction service support
L-Band reception supports satellite-delivered correction workflows such as Galileo HAS and other compatible PPP services.

Frequently Asked Questions
Answers for survey and integration engineers.
Practical answers about receiver compatibility, external antennas, L-Band, mounting, installation, and project orders.
What makes ZENITH different from a standard GNSS patch antenna?
ZENITH is designed as a survey-grade full-band GNSS antenna rather than a basic L1 patch antenna. It supports multi-frequency reception across major constellations, provides stable phase center behavior, includes an integrated LNA, and is built for outdoor RTK, monitoring, base-station, and precision positioning workflows.
Which GNSS receivers can ZENITH work with?
ZENITH is intended for RTK, monitoring, and survey-grade GNSS receivers that support an external active antenna. The receiver must provide suitable antenna bias power and use a compatible antenna input through the appropriate TNC-to-X cable.
Is the cable included?
No. The cable is not included. Select the correct TNC-to-X cable based on your receiver connector, such as TNC-to-SMA, TNC-to-MCX, or another compatible cable type.
What is L-Band used for?
L-Band reception is used by satellite-delivered correction workflows and PPP services. If your receiver and service subscription support L-Band corrections, ZENITH provides the antenna-side reception capability needed for those workflows.
Does ZENITH require antenna bias power?
Yes. ZENITH is an active GNSS antenna with an integrated LNA, so it requires DC antenna bias power from the connected receiver. The supported operating voltage is DC 3.3V to 12V.
Can ZENITH be mounted on a standard survey tripod?
Yes. ZENITH uses a 5/8"×11 TPI survey-standard mounting thread, which is compatible with common survey tripods, poles, and mounting accessories using that standard.
Is ZENITH suitable for permanent outdoor installation?
ZENITH is built with an IP67 outdoor-rated radome and supports an operating temperature range of -40°C to +85°C. It is suitable for outdoor RTK, monitoring, and reference-station style deployments when installed with proper mounting and cable protection.
Does ZENITH need a ground plane?
ZENITH can be used on standard survey mounts and receiver installations. For fixed monitoring or reference-station deployments where maximum stability is required, follow the receiver and site installation recommendations for antenna placement, multipath reduction, and mounting environment.
What should I check before ordering?
Check that your receiver supports an external active GNSS antenna, provides compatible antenna bias power, and has a suitable connector path through a TNC-to-X cable. Also confirm whether your workflow needs L-Band, E6, or specific multi-frequency support.
Is volume pricing available?
Yes. Volume pricing is available for project orders, fleet deployments, monitoring networks, and distributor inquiries. Share the expected quantity, shipping destination, and project timeline when contacting Kalmix.
