n3ujj.comUse of a dipole on several bands • It is possible to use a center fed dipole over a wide range of frequencies by: – feeding it with low-loss transmission line (ladder line) – providing impedance matching at the transceiver • The lower frequency limit is set by the capability of the matching network. Typically a dipole can be used down to 1/2 of its resonant frequency.

These two out-of-phase signals cancel each other out along the length of the coax, preventing it from radiating, and delivering almost all of the RF energy to the antenna feedpoint.
