Is there a way to estimate how long an antenna is? Answered
If I built a radio transmitter and then attached it to an antenna of unknown length, is there a way to calculate the length of it using transmissions? Or, as a separate question, if I had an antenna of known length and then increased or decreased the length, would there be a way to estimate the new length from transmission properties (basically without physically measuring the antenna? Assume the antenna is a straight line.
