Dipole antenna calculator.

for a Dipole or Inverted Vee Antenna. This calculator uses a "K" multiplying factor value of .975 to adjust for the. effect of antenna wire diameter on length which is applied to the free-space. half-wavelength equation. This works very well with #18 to #12 wire sizes.100 kilohertz. Series matching the 35 foot high antenna barely affects its bandwidth at all. An 80 meter dipole at that height is radiating most of its energy nearly straight up, so it is not an effective antenna for other than short range contacts, leaving aside how many such antennas it would take to cover the whole band satisfactorily.The basic formula for determining the length of a full-wave wire Loop antenna is: 1005 ÷ freq (mHz) = Length (feet). Since closed loops are not subject to "end-effect" the calculated physical lengths with this formula are longer than corresponding dipole dimensions and are close to free space dimensions.The dipole antenna has two wires. Each wire has one end connected to antenna and the other end is left free. The free end of each wires are pointed towards opposite direction of the other free end.
