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

[Tom Osborne]

I think a tuner only fools people to think things are working right 
(unless you use a Matchbox type tuner and twinlead).

If I have a RG-8X feeder, and I operate a 10 meter CW antenna at 28.900, 
the amp may be happy and putting out it's power, but most will be 
getting lost on the way to the antenna.

Yes, it will work, but not efficiently.  73
