[Elecraft] K2 Tuner?

[Leigh L Klotz, Jr.]

That will work OK for QRP battery portable, but it is floating your rig 
chassis above RF ground.  In the shack with a power supply, the power 
supply and its ground will become part of your antenna and will radiate, 
perhaps degrading performance.

To see the effect, test if you get different SWR (or RX sound) when 
touching the rig vs. not touching it.  A balun even at the base of the 
rig, or on a short coax jumper, will eliminate these effects.
