WebA standard off-center fed dipole will have its resonant freq at about 3.5 MHz. The OFC-3K75 uses a coaxial capacitor on the long side of the antenna wire, to raise the resonant frequency to about 3.8 Mhz which is about the midpoint of the SSB portion of the band. All the other bands (40/20/17/12/10) are not affected. WebSometimes they work on second harmonics (i.e., 10m and 20m), especially dipoles. So your 60m antenna may work on 30m and 15m.
