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.
14 maj 2020 · How does a single FM antenna length work in the entire FM frequency band range, when there are theories which state that the antenna size should always be close to wavelength/4 for proper reception & transmission? For example: The FM frequency band ranges from 88 MHz to 108 MHz.
19 sty 2017 · I want to use an end-fed wire antenna, but what would be the best length of wire for the 20m and 40m bands? Is there a way to work this out? This is assuming a tuner will be used.
Includes calculated K and end-effect factors. 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.
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 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 ...
The Single Wire End Fed Antenna is probably the simplest antenna to use. But when you start looking around, you find that no one can agree on what length to use. Some say any length will work, some stress odd multiples of 1/4 wavelength, while others lean toward even multiples of 1/2 wavelengths. Some say design for the lowest frequency ...
