The X7 Triband Yagi is geared to set new
standards in both radiating performance and mechanical reliability. The
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. Each mechanical
component was designed to 100+ MPH wind survival with a 1.25 safety
factor. Traps were eliminated from the high current driven elements and
reflectors using the new 4L Log Cell design, which 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 which
will easily handle the legal limit.
• 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
