[Drake] Need Input on the MN-2700 Tuner

[Bob Camp]

Hi

The Johnson was designed in an era of 450 ohm ladder line antenna feed. 
It is at it's best when you try to feed something outlandish like a end 
fed dipole. High SWR and high impedance are a much better combo for the 
Johnson than they are for a balun based tuner. The problem isn't the 
tuner it's the balun ...

As long as you are running things that are fairly close to resonance 
there is nothing at all wrong with either a balun or the MN-2700. I 
have always questioned just how effective any 10:1 SWR antenna may be 
....

	Take Care!
