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.
2.1. 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.
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.

Find the optimal antenna length for your VHF frequency with these cutting charts. Choose from various antenna types, mounts, and springs for different operating conditions.
29 kwi 2020 · Learn how to choose the ideal VHF antenna length for your radio by following the wavelength rule. Find out why antenna length matters and how to position and angle your antenna for optimal signal.
Introduction. Remember that frequency is inversely proportional to wavelength. Many antennas are measured in terms of the fraction of a wavelength at the frequency of operation. Engineering methodology and higher math will not be covered in this presentation (whew!). Antennas for Portable (HT) use . Single. stock.
