Whip Antenna Length And Frequency Calculator

This calculator requires the use of Javascript enabled and capable browsers. This calculator is designed to give the vertical length (height) of a particular whip type antenna, or the frequency of it. Enter one (only one) value, the desired frequency or the antenna length in any length field. Click on Calculate and the opposite value will be displayed in feet and inches or frequency in megahertz (Mhz). These are considered as generic calculations and you may wish to use them to learn general information about the antenna structure you are contemplating. Click on Clear Values to prepare for new calculations. Any antenna created with this calculator MUST be fine tuned for VSWR. None of the calculations are rounded or massaged and all calculated results are raw data.
