High Gain and Wide Coverage for Demanding Scenarios
Understanding the Antenna’s Performance Advantages
Performance wise, the 225-400MHz Wideband Antenna stands out with a prominent high gain feature. Its overall gain exceeds 6dBi, with even more impressive specific outputs at key operating frequencies—7.6dBi at 225MHz and 8.8dBi at 400MHz. This exceptional gain capability, combined with a 3dB beamwidth ranging from 60° to 125°, allows the antenna to maintain long-distance signal transmission while covering a broad receiving area. This dual advantage effectively eliminates signal blind spots, ensuring robust connectivity over expansive zones. Additionally, the antenna supports a maximum carrying capacity of 100W/800W, meeting the demands of high-power signal transmission without compromising performance. The low VSWR of 1.5 (typical value) further reduces signal reflection loss, significantly improving overall energy utilization efficiency. For RF engineers, this translates to a device that not only delivers powerful signals but does so with minimal waste, enhancing system reliability.
