Antenna callculators

OCFD Dimensions, Design & Plans. Calculate the total length, short leg, long leg and feedpoint position for an off-center-fed dipole. Choose a band or custom frequency, select the OCF split, and use the results as a starting point for building and tuning your antenna.

Calculate section lengths for a multiband linked dipole, standard dipole, or inverted-V antenna by frequency. Enter the HF bands or exact operating frequencies you want to use. The calculator returns the starting cut length for each dipole leg, individual linked sections, link positions, and the complete active antenna length for every band. Linked dipole geometry […]
