As a high-performance communication device designed specifically for professional RF scenarios, the 225-400MHz Wideband Antenna operates stably within the frequency range of 225MHz to 400MHz thanks to its wideband coverage feature, making it perfectly suitable for various scenarios with high requirements for signal bandwidth and stability, such as communication systems, radar auxiliary signal transmission, and industrial control. Its core product type is the Log-Periodic Antenna, a design that endows it with excellent wideband impedance matching capability and uniform radiation characteristics, effectively reducing signal attenuation at different frequencies and ensuring consistent communication quality across the entire frequency band.
In terms of performance, this antenna boasts the advantage of high gain, with an overall gain of more than 6dBi, and can achieve even higher gain output at key operating frequency points (e.g., 7.6dBi at 225MHz and 8.8dBi at 400MHz). Combined with a 3dB beamwidth of 60°~125°, it not only ensures the long-distance transmission capability of signals but also covers a wide receiving range, avoiding signal blind areas. At the same time, it has a maximum carrying capacity of 100W/800W, which can meet the demand for high-power signal transmission, while the low VSWR of 1.5 (typical value) further reduces signal reflection loss and improves energy utilization efficiency.
In terms of structure and environmental adaptability, the antenna is made of high-quality Alufer material, which combines lightweight and high-strength properties. Coated with army green, it is not only corrosion-resistant and wear-resistant but also maintains stable performance in complex outdoor environments. Its operating temperature range reaches -55℃~+75℃, and the storage temperature range extends to -65℃~+85℃, allowing it to operate reliably even in extreme high and low-temperature environments. It adopts a panel installation design, with reference dimensions of 1270mm×770mm×146mm, balancing installation convenience and space adaptability. Additionally, equipped with an N/L29 type connector, it can quickly achieve a stable connection with various RF devices, reducing installation and debugging time. Whether for signal relaying in industrial sites, signal coverage of outdoor communication base stations, or auxiliary signal transceiving in radar systems, this Log-Periodic Antenna can meet strict application requirements by virtue of the wideband advantage of the 225-400MHz Wideband Antenna and the performance highlight of high gain, providing users with a stable and efficient signal transmission solution.
