Half wave dipole length calculator

Friday, 9th October 2015

This calculator takes a frequency in MHz and gives the total length of the dipole and then the size each element should be.

This uses a metric conversion of the ancient 468 constant, conventional wisdom is that you take the value you get and add "a couple of feet", fire it all up and trim the elements bit by bit while taking note of the SWR as you do it.
