SWR: Frontend Data Fetching and Caching by Sunny Yang

WebSep 1, 2024 · This chart serves as an aid in trimming the length of HF antennas. The chart estimates, over the length of an approximate quarter wavelength, the required change in length to shift the fundamental antenna resonance by a specific amount of kHz. Always start out with an antenna that is too long, i.e. resonant below the desired resonant frequency. http://kv5r.com/ham-radio/coax-loss-calculator/ how to exit out tab
