Radiation patterns, polarization patterns, VSWR charts, antenna currents diagrams and Smith charts. For each of the antenna types currently supported, any combinations of the following charts and diagrams can be generated and displayed: azimuth and elevation radiation patterns; 3D radiation patterns;
28 kwi 2023 · Given the high quality of today’s transceivers, the most important station component is the antenna system that starts at the RF connector of your radio and ends a wavelength or two away. Gains and losses anywhere in the system affect signal strength.
The antenna radiation pattern strongly depends on the length and height. In the examples below I hope to make the differences clear.
20 kwi 2003 · Following is a series of dipole radiation pattern plots, produced by a popular antenna modeling program. The first plot below shows a dipole at an elevation of two wavelengths above a standard earth ground model. Note the multiple lobes at varying elevation angles above the horizontal.
We will discuss the different types of antennas commonly used by amateur radio operators, including wire antennas, vertical antennas, and Yagi antennas. Additionally, we will explore the key factors to consider when selecting an antenna, such as frequency range, gain, and radiation pattern.
THE HAND-HELD RADIO ANTENNA DILEMMA – 4 – •Adding appropriate lengths of radial material at the base of the antenna provides a ground plane for improved radiation pattern and counterpoise for known RF current return path. (C)2016 - NO1PC, JIM ASPINWALL
27 wrz 2020 · CloudRF has a large database of 3D antenna pattern templates (Azimuth and Elevation planes) which all users get free access to. Using a pattern greatly enhances your planning accuracy as it simulates your hardware’s true radiation capability. You can even upload your own pattern in ADF format.
