XM - 10, 15 & 20 Meter 5 Element Yagis. Cushcraft announces new 5
element Monobanders for 10, 15 & 20 meters. Each XM model has Big Thunder
hardware and high wind ratings. Phillystran boom trusses are used on the 20
meter model. The feed systems are 50 ohm direct feed - dual driven elements.
VSWR is flat across the band. A high power 1:1 balun is included. Big Thunder
Monobanders were Beta tested at three extreme bad weather sites for the winter
1997/1998 season. They have excellent patterns and are perfect for stacks.
Outstanding performance thanks to Cushcraft’s unmatched multiband design technology and experience.
Rugged stainless steel mounting hardware is easy to install and maintain.

XM240 - 40 Meter 2 Element Yagi. The famous 402CD two
element 40 meter beam is now redesigned as the XM240. It features
the same contest winning performance with a 90+ mph wind rating.
A 2-1/2” OD boom and Big Thunder style 3/16" thick extruded element
and boom plates are used to eliminate mechanical failures. A Phillystran
boom truss and 1:1 high power balun are included.
Big Thunder Monobanders
Cushcraft’s newest vertical antenna offering omnidirectional coverage on the popular 2 meter, 6 meter and 70 centimeter bands is a great idea for someone
with limited space or in need of an antenna that can be easily knocked down and transported. The AR6270B is a great choice for mobile home use. The
antenna offers 2dBi of gain 6 meters, 5.5 dBi on 2 meters and 7.5 dBi on 70 centimeters.

A627013S 6 Meter/2Meter/70 Centimeter
Cushcraft’s newest multiband directional yagi is designed to provide hobbyists
who have limited tower or mast space with directional antenna performance on
three of the most popular bands. The A627013S combines 6 meters, 2 meters
and 70 centimeters on one boom. Since the three antennas were designed to
share a common boom, the A627013S solves the often encountered problem of
degraded antenna performance due to inadequate spacing when using separates.
