SWR CURVE
The rotatable dipole is built on the full-size 30m base dipole, therefore, it can also become a dual-band antenna with the aid of a remote switching system, even a self-built one. The linear loading system (no power limit) maintains the correct reduction ratio of 30% within which there are no significant losses compared to a full-size dipole. It also makes it easy to choose the band portion on which it is preferred to optimize it by operating at the center of the dipole and not at the ends.
