Does this mean that I build a bridge of some kind and feed it with low power RF from the transmitter? Is there a way to calculate it by taking readings at the antenna with a scope?. E, I and Phase angle? Should I take the readings, from the top of the loading coil to ground? I can run the power down to almost nothing if needed. J.
