Four Star Full Frequency Measurement Antenna with TNC Female Interface for RTK IoT Applications

This Four Star full frequency measurement antenna is designed for high-precision centimetre-level RTK positioning in Internet of Things (IoT) environments. Featuring a side outgoing line with a TNC-K female interface, it simplifies cable management and installation in space-constrained locations. The antenna's copper nickel-plated contacts ensure consistent signal transfer, while the IP67 rating provides reliable operation in dusty or wet conditions. With support for both threaded and magnetic suction mounting, including a strong magnetic black base option, this antenna adapts to various professional setups. As part of the STARF measurement antenna series, it is built for demanding positioning tasks where accuracy and robustness are essential.

Features and Construction

This antenna is engineered for reliable performance in high-precision positioning scenarios. Its construction prioritises signal integrity and environmental resilience, making it suitable for both fixed and temporary installations.

Material and Build

The contact material uses copper nickel plating, which provides good electrical conductivity and corrosion resistance for extended use. The housing and base are designed to meet IP67 standards, meaning the antenna is dust-tight and can withstand immersion in water up to 1 metre for 30 minutes. This build quality ensures dependable operation in outdoor or demanding indoor environments without additional enclosures.

Size and Practical Fit

The antenna weighs approximately 1kg, making it lightweight enough for temporary magnetic suction mounting yet substantial enough for secure threaded installation. The side outgoing line design reduces the overall footprint and allows the cable to exit at a convenient angle, which is particularly useful when mounting on metallic surfaces or in tight spaces. The TNC-K female interface is a standard choice for professional RTK equipment, ensuring compatibility with many receivers and cables.

Uses and Placement

This antenna is specifically designed for high-precision RTK positioning, commonly used in surveying, mapping, and IoT infrastructure. Its versatile mounting options make it suitable for both permanent and mobile installations.

Event or Professional Use

For professional surveyors and GIS technicians, the antenna's full frequency coverage supports multi-constellation GNSS signals for centimetre-level accuracy. The magnetic suction base is ideal for temporary setups on vehicles or metal roof surfaces during field surveys, while threaded mounting provides a permanent solution for base stations or reference points.

Everyday Home Use

While primarily a professional tool, the antenna can be used by advanced hobbyists in precision agriculture, drone base stations, or property boundary mapping. Its simple installation and robust IP67 construction mean minimal maintenance even when left outdoors. The side outgoing line keeps cables tidy and reduces trip hazards or snagging.

Benefits and Buying Value

This antenna offers clear advantages for users who require consistent, high-precision signal reception without complex setup. Its design focuses on durability, ease of installation, and reliable connectivity.

Reuse and Low Maintenance

The IP67 rating reduces the need for frequent cleaning or protection from weather, allowing the antenna to be left in place for long periods. The copper nickel-plated contacts are resistant to oxidation, so signal degradation over time is minimised. With no moving parts and a sealed body, the antenna requires only occasional visual inspection and cleaning of the mounting surface.

Why Choose This Product

This Four Star antenna combines full frequency RTK capability with a practical side outgoing line and IP67 protection. It is a focused solution for professionals and advanced users who need a reliable, easy-to-install antenna for centimetre-level positioning without unnecessary extras. The choice of threaded or magnetic mounting adds flexibility without compromising performance.
