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.
7 paź 2024 · The FM band is not a single frequency. Instead it extends from 88 MHz to 108 MHz. For the purpose of the calculation, we can choose the center of the band at 98 MHz. The length of a quarter wave antenna for FM applications is 76 cm.

14 maj 2020 · The answer to your question would be that reception across the 88-108 MHz FM band would be possible using a single log-periodic antenna specifically designed for the FM band and having a bandwidth of 20 MHz.
30 lip 2024 · Dipole FM antenna length and construction FAQs. Our dipole calculator is a simple tool that allows you to compute the length of a simple antenna — it'll also provide you with the value of the wavelength and the adjustment factor [k].
In this section, we will explore real-world examples of calculating antenna length, different scenarios and their corresponding calculations, and how to optimize antenna length for specific FM radio setups.
23 sty 2024 · For each band, I will provide a typical wire length for one side of a dipole for the target frequency, which is usually the bottom edge of the band, along with expected variance, recommended starting wire length, expected SWR bandwidths, length of the hanging tails, and an estimate of the change in wire length to shift the frequency by 100 kHz ...
