10, 15, 20 Meters - 9 Elements on a 28 ft. (8.6M) Boom
(Optional 40 M kit)

10, 15, 20 Meters - 7 Elements on a 18 ft. (5.5M) Boom
(Optional driven element for 40 M)

New High Efficiency Computer Optimized Design for Maximum Gain and Ultra Clean Radiating Pattern
100+ MPH Construction for Best Reliability and Long Life
NEW 4L Log Cell Driven Elements for better VSWR Bandwidth
Trapless Driven Elements and Reflectors for Reliable Power Handling
Interleaved Element Design for Mono-Band Performance
Add-on kits available for 40 Meters

The new X9 and X7 Triband Yagis are geared to set new standards in both radiating performance and mechanical reliability. Cushcraft's product development team has employed the latest computer modeling technology to achieve a superior electrical design as well as elegant new mechanical hardware and assembly techniques.

Super rugged boom to element clamps.

Each mechanical component was designed to 100+ MPH wind survival without a boom truss with a 1.25 safety factor. Traps were eliminated from the high current driven elements and reflectors using the new 4L Log Cell design. This yields virtual monoband performance and maximum power handling capability. Traps are employed only in the lower current directors for increased gain and sharper pattern. The result is a truly high performance antenna family which will easily handle the legal limit.

Boom to mast clamping speaks for itself .
