[TowerTalk] RG-149: 50 ohm/70 ohm - does it matter?

Hi....

I work in hospital administration.  My ugrad degree is in Biology and my 
masters degree is in healthcare administration.  In other words, I'm no 
engineer.

However, I took a look at Mikes home page and it seems like he has a "simple" 
antenna setup (ie, no stacks = no phasing concerns).

So what's the diff if it's 50/52/70/75 ohm feedline?  The mismatch (if not 50) 
will be "nothing" and therefore the extra loss will be "nothing."  Transmission 
line is always transmission line.  As long as the line itself is not "lossy," 
does it matter?

Looking for sage advice for those with degrees or prowess in this area.
