How long does 6m dipole antenna last?
How long does 6m dipole antenna last?
It’s small, only about 9 feet 4 inches from end to end, (see drawing below article) so it can be configured for other bands as well. I used the standard formula for a dipole (468 / Freq mhz = total feet. The lengths in the drawing below are for 50.1mhz.
Will a 10m dipole work on 20m?
I don’t hear any difference in noise level between having the antenna plugged in and not. Even stranger is that I would expect this antenna to work fairly well on 10m too. A half wave dipole for 20m should be a full wave dipole for 10m, so it should at the very least receive well on 10m.
How do you calculate antenna length?
Divide the optimum antenna length by two if you are using a dipole antenna, which simply means “two poles.”. The result is the optimum length for each of the two poles. (Alternatively, just divide 234 by the frequency.)
How do you calculate the length of a dipole?
Enter the desired operating frequency in megahertz to get a good starting length for a dipole in both feet and meters. The formula for calculating the approximate length of a dipole is: Dipole length in feet: 468 / frequency in MHz. Dipole length in meters: 143 / frequency in MHz. These are only approximate values.
What is the length of a dipole antenna?
Hence, the half-wavelength dipole antenna’s length is 0.25 meters. The half-wave dipole antenna is as you may expect, a simple half-wavelength wire fed at the center as shown in Figure 1: Figure 1. Electric Current on a half-wave dipole antenna.
What is the length of antenna?
Rather than bore you with all the specs for these antennas, basically the 2m antennas are about 19 feet long and the 70cm antennas are about 10-14 feet long. The gain on the 2m antennas is about 11-15db and the gain on the 70cm antennas is about 15db. As you can see, all the antennas are roughly the same length.
