Loop antenna resonant frequency calculator
The simple calculator below uses the well-known standard formula for determining the total wire length in feet for a single element
Logarithmic Periodic Dipole Antenna Calculator
The javascript starts with the minimum value of = 0.76. If a solution could be found, is increased as long as the length of the boom
Magnetic Loop Antenna Calculator
Magnetic loops or mag loops, can give surprisingly good performance when they are carefully designed and constructed

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
