Unless the antenna system is starved for background noise, or the element is 
in an end-fire phased array, it makes very little difference. The only real 
effect of mismatch is signal and noise from the antenna drop equally. 
Outside of a low sensitivity array, or an array that is phased end-fire, 
until background drops with 10 dB of RX system noise floor, or preamp noise 
floor, it really doesn't matter.

Two turns for 75 ohms is plenty for decent 100 kHz to 30 MHz performance.

Now if you hook up a Sky Buddy, it's a different problem.  :)
