Find the optimal length of antennas for different ham bands in feet and meters. The chart shows the wavelength, half wavelength, dipole and loop antennas for each frequency range.
· An antenna wire of 18.7 mtr in total length with 15.7 mtr installed horizontally at 2.5 mtr above the ground and with a 3 mtr 30 degrees angled lead in section to the RF source or the graphed impedance load point.
Learn how to avoid the worst lengths for random wire antennas on different HF bands and find the best ones for low swr and good loading. See a table of lengths to stay away from and a list of recommended lengths in feet.
Find recommended wire lengths for different HF bands and unun models in a table format. Learn how to install the antenna wire as an Inverted L or with a counterpoise or ground and how to use a choke balun for best performance.
The "Best" Random Wire Antenna Lengths Randon wire lengths you should and should not use! The random wire antenna is probably one of the least expensive, easiest and
This calculator is an aid for determining antenna element lengths, based on Frequency, Type (Wire or Tubing), and Diameter (AWG#, inches, mm) of the element. At the top of the calculator, enter the Frequency (1 to 30 MHz) of interest.
