This multiband vertical designs provide 9 band coverage
encompassing the 6, 10, 12, 15, 17, 20, 30, 40 and 80 meter bands. Cushcraft
achieved a major breakthrough in the development of an HF multiband vertical
antenna that has been specifically designed for use with a tuner and amplifier.
As a result, the antenna more accurately addresses the needs of the contemporary
ham shack.
Multiband vertical antennas have always been complicated designs
with components as likely to be damaged by high levels of mismatched transmit
power as the rigs they are attached to. Before the use of tuners became
widespread, the antenna was protected by the same safety mechanisms that
protected the rig. Now, the automatic power reduction circuits of the past have
actually become a second layer of protective circuitry. Although the auto-tuner
provides the ham with a more versatile device as well as protecting the rigs
components, the antenna is more vulnerable than ever. With the press of a
button, very high loads can be imposed on the antenna. The result to the antenna
can be catastrophic failure in some instances.
Although the antenna is best operated within its 2.0:1 VSWR
bandwidth,it can sustain a 3.0:1 VSWR mismatch at full power for typical
operating intervals. Now radio amateurs can take full advantage of the
versatility that a tuner used in conjunction with a multiband HF vertical
antenna can give them. For high wind environments, add the R-8GK, Guy kit-three
point non-conductive guy system.
