A One Trim Dipole Calculator

We, as Hams have experienced building wire antennas and have run up against the chore of calculating the lengths of wire for our desired operating frequencies. Here is a calculator that makes this task easy. You can build a single band, dipole antenna and have it resonate where you want it with (most likely) one trim instead of the usual two or more times. The calculator does not require installation and will run on any device that can download it from this website.
