  1. 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.

  2. 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.

  3. 5 cze 2021 · 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. This formula to obtain the length of a half-wave dipole antenna will give a good ballpark value to start with.

  4. 1 wrz 2021 · This chart serves as an aid in trimming the length of HF antennas. The chart estimates, over the length of an approximate quarter wavelength, the required change in length to shift the fundamental antenna resonance by a specific amount of kHz.

  5. 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...

  6. The random wire antenna is probably one of the least expensive, easiest and cheapest HF antennas to use if you have a tuner and you want to get the "most" out of a length of "random" wire without having to pull out that calculator, doing the math, getting the center insulator built or bought, running the feedline, and all the rest that goes ...

  7. 30 lip 2024 · To calculate the length of an antenna, you may use the formula: L = 468 / f. l = L /2. where: L — Length of the dipole antenna; l — Length of each arm of the dipole; and; f — Frequency. Dividing 468 by the antenna frequency will give you the length of the antenna in feet.
