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.
14 maj 2020 · With high power FM transmitters located in the heart of a city, a 75 cm length of wire would suffice to receive stations across the band. In the case of a receiver with a telescopic antenna, it's length could be adjusted, if required, to receive weaker signals.
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.
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.
The impedance of a end fed wire can be anywhere from a few 10s of Ohms to a few thousand Ohms, depending on the frequency in use and the length of the wire. Other factors that can affect the impedance are bends in the wire, height above ground, proximity to buildings and wire diameter.
7 paź 2024 · In this post we provide a calculator that gives the length of an antenna that can be used in the Frequency Modulation (FM) Band.
