Plugin Name: K5HH Ham Radio Calculators


I’m creating a series of calculators in service to amateur radio operation.

First is the Dipole length calculator. This calculator is built using the formulas I found at . If you wish, use them for figuring out this math for yourself.


The dipole calculator allows your website visitors to find the resonant length of their dipole antennas on the second raise.

*** Disclaimer ***

The K5HH Antenna Calculators are for demonstration purposes only and may not reflect actual numbers for your equipment. I have, in good faith, given my best efforts to provide a calculator that will save ham operators time in setting up their antennas. However, ultimate responsibility for the proper use of your equipment lies with you.


  • This is the halfwave Dipole length calculator.
