End feed dipole ham antenna
WebJun 3, 2024 · Observations: Both the end-fed and center-fed antennas operate just fine without any additional conductors or feedlines. The end-fed energy is less than the center-fed. If you do the math, it emits about 1.6 … WebDipole Antenna Calculator. The measurements below are for building a simple Dipole Antenna. The Wire Size can range from 16 AWG to 12 AWG. The larger the wire, the wider the bandwidth. The antenna is designed to be fed with 50 or 75 Ohm Coax Cable of most any length with a Balun. Place a 1:1 Balun on the Antenna end of the Feedline.

WebMar 8, 2024 · the original fan dipole; trap dipoles; off-center or end feeding; changing the effective dipole length; harmonic resonances. A dipole will present a low feedpoint impedance when each leg is close to an odd multiple of 1/4 wavelength. This is commonly used to operate 15m using a 40m dipole, or 10m using the 7th harmonic resonance with … WebJun 5, 2024 · The most widely used formula to calculate the approximate overall length of wire required for a dipole is: 468 / frequency (MHz) = length of wire in feet. The antenna calculator above uses this formula as a starting point to calculate wire lengths for the dipole. The results are conveniently displayed in inches, centimeters, feet and meters.
