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 rig’s 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.
