Web21 aug. 2024 · Constructing a dipole is an easy and versatile project that can be done with 10 to 18 gauge copper wire. This means it will work for any antenna, whatever the frequency range and size are. Copper wire comes in both stranded and solid form, which means you have the option of bare or insulated wires as well! 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 … Meer weergeven The half-wave dipole is two equal lengths of wire with the feedpoint in the center.
