Formula & Equations for inductance of air core inductor Calculator Inductance of an Air core coil inductor L = (N2 x d2) / (18d + 40l) … μH Where, N = Number of turns, d = Inductor Coil Diameter, l = Inductor Coil Length.

433 MHz Coil Loaded Antenna: In my 433 MHz projects I have been using a cheap (0.70 cnts) pair of Tx/Rx modules. I have mostly used the transmitter and that is actually fairly OK with just a simple 1/4 lambda antenna, but is open for improvement The receiver however is a bit cr…
