<p>Gostava de ter uma!!<br>
Mas aqui na beira serra onde os ventos atingem com facilidade
mais de 100K/h não a devia ter em pé por muito tempo<br>

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.</p>
<p>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.</p>
