High precision Dual-Band TNC-K Connector GNSS Antenna GL234C

Product Introduction

1. Dual - Band Frequency Coverage：The GL234C GNSS antenna covers two important frequency ranges: 1559.052 - 1616MHz and 1205.094 - 1278MHz. This dual - band design allows it to receive signals from multiple GNSS satellite systems simultaneously, enhancing positioning accuracy and reliability.

2. Good Radiation Performance：With a peak gain of ≥3dBi, a horizontal coverage angle of 360°, and a vertical coverage angle of 5° - 90°, the antenna can effectively capture GNSS signals from various directions. The RHCP polarization and an axial ratio of ≤3dB also contribute to stable signal reception, reducing signal interference.

3. Low Signal Loss：It has a V.S.W.R of ≤2.0, which ensures efficient power transfer and minimizes signal reflection. The low noise figure of ≤1.5dB and passband fluctuation of ±1.5dB further guarantee that the received signals are of high quality, with minimal degradation.

4. Versatile Mounting Options：Featuring magnet and screw mounting methods, the GL234C can be easily installed on different surfaces. The magnetic mount allows for quick and convenient attachment to metal surfaces, while the screw - mount provides a more permanent and stable installation option.

5. Rugged and Durable：With an IP67 ingress protection rating, the GL234C is dust - tight and can be submerged in water up to 1 meter for 30 minutes. It can operate in a wide temperature range from - 40 ℃ to +85 ℃ and withstand high humidity up to 95% (non - condensing), making it suitable for use in harsh environments.
