Typical SWR plots of the Model DX-CC antenna at a customer site. These were supplied by Gene, K5QXR and used with his permission. The antenna at his QTH was installed at 32 ft. on one end and sloping down to 24 ft. on the other in a clear setting. Gene says heʼs going to shorten the 20 meter sections a bit to bring the frequency up. The minimum SWR on 80 meters may be due to the nearness to the ground for that band. Your SWR plots may be different based on your installation site conditions (height above ground, surrounding objects, etc.)

The Model DX-CC is a shortened HI-Q antenna designed to maintain high efficiency on 80 meters (82 ft. long vs 130 ft. long for a full size 80 meter dipole). As a result, the loaded HI-Q design has a narrow SWR bandwidth of about 65-75 kHz on 80 meters. When set to the end of the band of choice (SSB or CW) it can then be broadened out across that section with a wide range antenna tuner. It is typically set at about 3825-3850 kHz from the factory, depending on installation site conditions.

Tests show our HI-Q design (made possible by our proprietary custom made coils, parallel wire design and components) permits near full size performance on 80 meters, as well as on the other design bands. The difference is typically within an “S” unit or less. The design is the most efficient we have seen and tested on ANY multi-band dipole. The HI-Q design technique is also used on our other multi-band models.

The Model DX-CC covers a portion of 80 meters, CW or SSB, and across much of 40, 20, 15 and 10 meters. 15 meters requires the use of a tuner since it works as a third harmonic of 40 meters. Customers report using 30, 17 and 12 meters with a wide range

tuner.
