Product scope
ZENITH is intended for engineering teams building professional GNSS systems that depend on stable multi-frequency reception. Typical deployments include RTK rover setups, local base stations, monitoring installations, surveying equipment, and precision field systems.
The active-antenna architecture integrates a low-noise amplifier and uses a TNC-K RF interface. System integration should account for the receiver-side antenna bias supply, mounting position, and installation environment.
Confirm the receiver input and antenna bias supply. ZENITH uses a TNC-K female connector. Review the Specifications page before system integration.
Engineering characteristics
The following characteristics summarize the antenna-level capabilities relevant to receiver compatibility, site planning, and system evaluation.
Full-band GNSS reception
Multi-frequency reception across GPS, BeiDou, GLONASS, Galileo, and L-Band for professional positioning workflows.
±2 mm phase center stability
Stable phase-center behavior supports measurement consistency in surveying, base-station, and structural-monitoring workflows.
Active antenna architecture
The integrated low-noise amplifier supports professional receiver systems designed for external active-antenna inputs.
Wide-beam sky coverage
Broad sky coverage supports low-elevation satellite tracking and improved satellite geometry in partially obstructed environments.
Survey-standard installation
The TNC-K connector and 5/8" × 11 mounting thread support common surveying, monitoring, and reference-station installation paths.
IP67 outdoor radome
The IP67-rated enclosure is designed for outdoor positioning, monitoring, and field-deployment environments.
Application fit
ZENITH is intended for precision positioning workflows that require an external full-band antenna, outdoor durability, and stable antenna-level performance.

Frequently asked questions
What is ZENITH designed for?
ZENITH is an active full-band GNSS surveying antenna designed for RTK rover setups, reference stations, monitoring installations, surveying equipment, and precision positioning systems that use an external antenna.
What receiver interface does ZENITH require?
ZENITH uses a TNC-K female RF connector and is designed for GNSS receivers with external active-antenna support. The receiver-side antenna bias supply should be confirmed before installation.
Which GNSS systems does ZENITH support?
ZENITH supports multi-frequency reception across GPS, BeiDou, GLONASS, Galileo, and L-Band. Review the Specifications page for the detailed frequency list.
Does ZENITH require antenna bias power?
Yes. ZENITH is an active antenna with an integrated low-noise amplifier. Review the Specifications page for the published electrical requirements.
Which mounting thread does ZENITH use?
ZENITH uses a 5/8" × 11 TPI survey-standard mounting thread. The interface is compatible with common survey tripods, poles, and accessories using that standard.
Is ZENITH suitable for permanent outdoor installation?
ZENITH uses an IP67-rated outdoor radome. For permanent monitoring or reference-station installations, use proper mounting and site-planning practices.
