News & Activities

The TQI-700/2700-SJ-02v02 is a top-of-the-line, ceiling-mounted indoor base station antenna designed by industry pioneer Tongyu for unmatched signal strength and coverage. An outstanding choice for indoor wireless systems, this antenna operates over large frequency bands—698 to 960 MHz and 1710 to 2700 MHz—supporting everything from LTE to 5G networks. Its vertical polarization and 360° horizontal beamwidth make it an indispensable part of indoor areas like transportation hubs, retail malls, and office complexes because they guarantee consistent signal dissemination in every direction.

Unmatched Electrical Performance for Reliable Connectivity

Tongyu's base station antenna model TQI-700/2700-SJ-02v02 boasts exceptional electrical performance that ensures stable and efficient communication across various frequencies. The antenna offers varying gain levels depending on the frequency band, including 1.5 dBi for 698–800 MHz, 2 dBi for 800–960 MHz, and an impressive 5 dBi for the 1710–2700 MHz range. With a vertical 3dB beamwidth of up to 80° at lower bands and 65° for higher frequencies, it guarantees excellent vertical coverage, which is critical for indoor penetration. The voltage standing wave ratio (VSWR) remains under 1.8 or ≤1.5, reducing signal reflection and maximizing signal transmission efficiency. With 50-ohm impedance and intermodulation distortion levels kept below -150 dBc, users can expect crystal-clear communication with minimal interference, even in high-traffic environments.

Built for Performance, Safety, and Longevity

Designed for both performance and durability, the Tongyu base station antenna handles a maximum input power of 50 watts at 50°C, allowing it to perform reliably under high-demand conditions. Its built-in lightning protection through DC grounding enhances safety and resilience, making it suitable for continuous, long-term use in various environments. The compact ceiling mount design ensures that it blends discreetly into any modern indoor architecture while delivering superior network coverage. This level of thoughtful engineering is a hallmark of Tongyu's commitment to providing world-class telecommunications solutions.
