So true, but be sure to measure the self- and mutual-driving-point
impedances to calculate network values that will produce equal currents at
the phase angles you require. In my experience, not doing so will produce
disappointing results.

I have successfully use the procedure outlined in Chapter 11, section 3.2.2
of ON4UN's "Low Band DXing" to do this several times.
