Notes:
This loaded dipole antenna calculator was developed to quickly estimate the inductance required for a coil-loaded dipole antenna, using
slider widgets.
Inputs via the slider widgets:
- f : The frequency of operation in MHz. [1.8-57.6 MHz]
- l : Length in percent compared to a half-wave dipole. Defaults to 80% of a half-wave dipole. [10-100 %]
- d : Distance of the coil/inductor from the feedpoint to the end, in percent. Defaults to midway from feedpoint to the end. [10-80 %]
- AWG : Conductor diameter slider changes wire thickness in AWG until AWG=0, then in mm for larger diameters. Actual diameter displayed in decimal inches and millimeters. [30-0 AWG, up-to 30mm]
Top left is the length of a single antenna element. (Not including the coil length.) Use this for vertical antennas.
Top right is the length of the entire dipole. (Not including the coil length.)
