Hmmmm, I wonder what 2% efficient means. 2% radiated power with 98%
reflected back into the radio? Ability to contact only 2% of the
stations that you can receive? What?


It's a ballpark estimate and means for every 100 watts going
into the antenna, two watts are radiated. If the feedpoint
impedance is 50 ohms, 98 watts are dissipated as heat in
the antenna, primarily in the coil(s). (Try transmitting 100w
into a 75m hamstick for one minute and then grabbing the coil.)
