  • Re : Additional resistance due to external losses, due mainly from capacitor contact resistance and proximity-to-ground effects. Use Re=0.0 to assume the loop is in free-space. Adding Re will reduce antenna efficiency, Q, Vcap and Ia, while increasing BW. According to [1] and [2], a 1 m diameter loop of 22 mm copper tubing at a height of 1.5 m above the ground at 7 MHz had a calculated capacitor contact resistance of ~190mΩ - and an additional ground proximity loss resistance of ~30mΩ. Note that ground effects are height-above-ground and frequency-dependent.
  • + and an additional ground proximity loss resistance of ~30mΩ. Note that ground losses are dependent on both frequency and height-above-ground.
  • Metric or Imperial : selects the measuring system.
  • Cu or Al : selects the type of metal conductor (annealed copper or aluminum).
  • Circ, Oct, Hex or Sqr : selects the shape of the magloop.
