3db is 50%, or one "S" unit - easy enough to notice. Actually, the
receiver capture ratio is the smallest amount you'll notice, so the
better the receiver, the smaller the change it takes to make a big
difference.


6 dB is the difference of one S-Unit. That's 25% of the Signal with one
more of S-Units.
For reception only purposes it's insiders knowledge to use _much_
cheaper lowloss tv-cable with 75 ohms runnig to a discone antenna. You
will hardly notice any loss for impedance mismatching as the impedance
curve of consumer grade scanners vary a lot from the 50 ohms.

Use the very best 50 ohm coax you can afford.
