WebGood SWR & Antenna Resonance. Standing Wave Ratio (SWR) is an important concept that describes how good of a match exists between a transceiver and antenna system. Recall that a perfect match corresponds to an SWR of 1.0, with higher values indicating some degree of mismatch. (See this article on SWR for more information.) WebMay 19, 2024 · Quad Dimensions. The Formulas for calculating quad element lengths (in centimeters) are as follows: Reflector Element ( L) = 78.5/Frequency ( Mhz ). Driven Element ( L ) = 74.5/Frequency ( Mhz ). Director Elements ( L ) = 70.8/Frequency ( Mhz ). If you don’t have a dip meter then once all the elements are in place the driven element may be …
