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.
23 sty 2024 · Likely range of lengths: 5.1 to 5.3 m ( 16.75 to 17.4 feet ) Suggested starting length: 5.35 m ( 17.5 feet ) Wire length change for 100 kHz: 3 to 4 cm ( 1.5 inches )
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.
The inverted Vee antenna legs will be longer by 2 - 6% from those of the horizontal antenna depending on the angle. This calculator assumes an apex angle of 90 degrees or 45 degrees from hoizontal for each leg and uses an increase of 5%.
Dipole Antenna Length Calculator The total dipole antenna length and the length of each dipole part can be obtained by using this calculator by just using the desired frequency of operation. Calculate the length of the dipole.
3 gru 2020 · That said, in case someone wants to try running a simulation on the antenna, the text below is a 4NEC2 model which will allow to play with the various parameters (wire diameters and spacing, arm lengths, antenna height) to see the effect they have on the pattern
Formula for the length of a shortwave half-wave dipole antenna in feet: L = 468/ f where L is the length of both legs of the dipole in feet and f is the desired frequency in MHz.
