Like Bill said, changing the coax length does not change the swr so there  
is very little "tuning" going on.
Using 1/4 wave or less will not fix the swr problem so something more is  
Changing from 50 to 75 ohm coax will cause some tuning to take place. Good  
luck finding a happy length though.

If you  change the length of the feed coax, you have created a "coax tuner".
1/4  wave or less is all that is required.
