Enter your desired frequency in MHz

After setting up your dipole with the lengths listed to the right, retest the SWR, find the frequency with the lowest SWR and enter that frequency in MHz below. New dipole length will show up below.

Desired Frequency:

Now reset the length of your dipole to the length below and you should be resonant on your desired frequency.

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. v1.1.0

Now reset the length of your dipole to the length below and you should be resonant on your desired frequency.
