Cushcraft X7 Big Thunder Tri-Band Beam Antennas have set new standards in both radiating performance and mechanical reliability. Cushcraft's product development team employed computer modeling technology to achieve a superior electrical design with elegant mechanical hardware and assembly techniques. Mechanical components of the X7 Big Thunders were designed for over 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 on 20, 15 and 10 meters. Traps are employed only in the lower current directors for increased gain and a sharper pattern. The results are truly high performance antennas that will easily handle the legal limit. Cushcraft X7 Big Thunder Tri-Band Beam Antennas are the serious DX operator’s choice, and for any Amateur who will never settle for second best on HF. Get your X7 now from DX Engineering.
