The X7 Triband yagi is a meticulously designed antenna that combines advanced computer modelling technology with superior electrical and mechanical engineering. This antenna is built to withstand harsh weather conditions with a wind survival capability of over 161 km/h (100 mph). The 4L Log Cell design eliminates traps from the high current elements and reflectors, resulting in exceptional performance comparable to a virtual monoband setup. Traps are only integrated into the lower directors, enhancing the antenna's efficiency.

The X7 Triband yagi is equipped to operate on the 10, 15, and 20-meter bands. It features seven elements and a power rating of 2kW. It boasts impressive specifications, including maximum gains of 12.5 dB on 20m, 13.0 dB on 15m, and 12.9 dB on 10m, with a front-to-back ratio of 30 dB. The antenna maintains a VSWR of 1.1:1 minimum and offers a bandwidth of 1.5:1 kHz on each band, ensuring reliable performance across different frequencies.

The X7 Triband yagi measures 5.49m in boom length and 63.5mm in diameter, and it is designed for optimal functionality. With a wind loading of 0.73 m² and a weight of 27.2kg, this antenna is both sturdy and lightweight. The X740 add-on kit is available for 40m, expanding the versatility of this high-performance antenna for amateur radio enthusiasts.
