rf

Calculate physical dimensions of a dipole antenna for a given frequency. Returns half-wave or quarter-wave element length in metres, feet, and inches. A half-wave dipole is the most common resonant antenna with approximately 2.15 dBi gain. A quarter-wave monopole (ground plane antenna) is half the length and is widely used in handheld radios and vehicle-mounted systems. Use this before building or purchasing an antenna to verify element length for your operating frequency.
