Cushcraft R-9 (B Grade Model)
9 Band HF/VHF Vertical Antenna
This is a Brand new R-9 that was sent to a customer - opened but NEVER erected - the packing box is "tatty" but most of the accessory packs inside have never been opened and it has NEVER been erected.
Great chance to grab a bargain!!
No ground system or radials needed, rugged construction, instant band changing, slim low profile silhouette
- This multiband vertical provides 9 band coverage 6, 10, 12, 15, 17, 20, 30, 40 & 80m bands.
- Ideal matching 2.0:1 VSWR however, it can sustain a 3.0:1 VSWR mismatch at full power for typical operating intervals
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.
Although the antenna is best operated within it?s 2.0:1 VSWR bandwidth,it can sustain a 3.0:1 VSWR mismatch at full power for typical operating intervals. Add the R-8GK, Guy kit-three point non-conductive guy system.
