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
