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.
22 wrz 2021 · Datasheets usually include graphs of antenna VSWR and return loss performance against frequency. Figure 1 illustrates the VSWR chart of a PulseLarsen antenna, with the optimum operating frequency range of 650MHz to 880MHz for cellular or ISM communications.
23 paź 2023 · Car antennas are supposed to deliver optimum performance without being an eyesore. However, their length is crucial and there may be capacitors & coils at the bottom of the antenna. The shorter ones are less efficient and they need extra electronic devices to step up their signals.
travel and experience significant attenuation before they reach an antenna mounted on your vehicle’s roof. When selecting an antenna, here are some explanations of the technical terms you will encounter and why they are essential. Bandwidth and impedance matching: Most antennas and transmission lines have a 50-Ohm impedance.
Watching different cars on the road in terms on antenna placements, it seems that there are a number of placements to be found. Figure 1 displays the best practices to place antennas to vehicles.
20 cze 2022 · The antenna is resonant when its length is equal to the wavelength (measured in meters) of the received or transmitted signal. For example, a frequency of 2,4 Ghz has a wavelength of 12,5 cm. In most cases, the effectiveness of an antenna is limited to a narrow band of frequencies.
