BIG THUNDER SERIES TRIBANDERS
X9 & X7
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.
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 family 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
Interleaved Element Design for Mono-Band Performance
