Cushcraft R8 multi-band vertical antennas provide 8-band coverage encompassing the 6, 10, 12, 15, 17, 20, 30, and 40 meter bands. Cushcraft achieved a major breakthrough in the development of an HF multi-band vertical antenna that has been specifically designed for use with a tuner and amplifier. As a result, the antennas more accurately address the needs of the contemporary ham shack. Multi-band 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. Cushcraft R8 antennas are the first multi-band vertical antennas designed for the rigors of contemporary operating conditions. Although the antennas are best operated within their 2.0:1 VSWR bandwidth, they 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 multi-band HF vertical antenna can give them. For high-wind environments, add the R8GK guy kit 3-point non-conductive guy system. Cushcraft R8 antennas provide 360 degree (omni) coverage on the horizon and a low radiation angle in the vertical plane for a better DX.
