The basic formula for dipole construction is dividing 468 by the desired resonant frequency, in MHz. As an example, a dipole cut for 14.225 MHz SSB is 468/14.225 = 32.9 feet total length. Divide 32.9 in half, and we see each element of this dipole needs to be 16.45 feet long. Meer weergeven There are many variations of the dipole antenna. For purposes of this blog, we will focus on a half-wave center-fed dipole with 50-ohm coax as the feedline.
