ljstevens Posted February 15, 2008 Share Posted February 15, 2008 Hi guys Quick thing can anyone remember the exact equasion for working out radio mic tx antenna lengths? Link to comment Share on other sites More sharing options...
patrick_keys Posted February 15, 2008 Share Posted February 15, 2008 Wavelength = speed of light / frequency. For instance, for a UHF radio mic centering on 863MHz will have a wavelength of 3x10^8 / 863000000 = 0.348m. Your ideal antenna is usually a quarter-wavelength, so somewhere in the region of 8.69cm for this example should do the trick. Link to comment Share on other sites More sharing options...
boswell Posted February 15, 2008 Share Posted February 15, 2008 This simplifies to Wavelength = 300/Freq in Mhz, Standard formula for amateur radio hams! Link to comment Share on other sites More sharing options...
