2.1. Antenna length based on the following formulars: 1/2 λ dipole (feet)= 468 / frequency in Mhz. 1/2 λ dipole (meters) = 142.65 / frequency in Mhz. Full wave loop (feet) = 1005 / frequency in Mhz. Full wave loop (meters) = 306.32 / frequency in Mhz. Cut wire slightly longer for connecting insulators and pruning. 22-Jun-2007 09:30 AM.
Ham Radio HF/VHF Antenna Lengths Chart. Here is a handy chart for determing 1/4 wave verticals, 1/2 wave dipoles, and full wave loop lengths. All antenna lengths in the information below are in feet and are the results based on the standard formula of 468 / FMhz = total length in feet.
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.
Cushcraft R7 Vertical AD4IE end-fed as inverted L. 1⁄2 wave antennas can be fed from the end (voltage feed) • Inverted L is popular on 160 and 80 meters where vertical height is often lacking. Many are 1⁄4 wavelength, but some longer, which allows easy multiband operation.
Antenna Length Calculator. 1. What type of antenna do you want to build? Dipole. Fan Dipole. Inverted Vee. Off Center Fed Dipole. Vertical. 2. What frequency will you be operating on? Frequency: MHz. Meters Feet. 3. Here's your antenna...
The VHF (Very High Frequency) range is 30 MHz to 300 MHz. Use this calculator to find the dimensions of a Dipole antenna designed to operate at this frequency range. A half-wave dipole antenna is comprised of two quarter-wavelength conductors placed end to end [1].
