Amateur Dipole Inverted
Vee Antenna Calculator

This calculator requires the use of Javascript enabled and capable browsers. This calculator is designed to give the total length of a particular dipole (inverted Vees) antenna, or one side of it, for the frequency chosen. Enter the desired frequency and select the desired calculation from the drop box. Click on Calculate and the optimum length for that combination will be displayed in feet, inches and fractions of inches, and in meters. The degrees of the inverted Vees are FROM horizontal. A standard dipole is parallel to the ground and is horizontal; a 15 degree inverted Vee is almost parallel to the ground while a 75 degree inverted Vee is almost perpendicular to the ground. Generally, 45 degree inverted Vees are the best compromise. Lengths are given in feet, inches and fractions of inches, and in meters. To optimize the antenna for a frequency RANGE, do the calculations twice, once for the low end of the range and once for the high end; then average the two and plan to adjust the VSWR on both ends of the range as needed.
