 From a student's point of view, most of the discussions on the subject 
start out with titles such as the importance of matching antenna to feed 
line.  A 50% error or 25% deviation does not seem trivial.

But from a practical standpoint, as 75 ohm coax is readily available, 
wouldn't it be better to use that?
