[Elecraft] Antenna Tuner versus Antenna Analizer ?

[O. Johns]

Paul,

As an addendum to the excellent summary by Bruce - W8FU, let me add  
that the Buddipole antennas are designed to match a 50 ohm coax feeder  
pretty well.  They are off-center fed to get near to the correct 50  
ohm impedance.  So if you use the K3 antenna tuner and the Buddipole  
you won't have too much loss in the coax line.  However, the Buddipole  
is a short dipole and as such not a particularly efficient radiator.   
You may find that with the 100 watts output of the K3 you will do very  
well with the Buddipole.  But at some later stage of your career you  
may want to have a longer piece of wire.  A non-resonant doublet of  
66ft or more fed at the center with 450 ohm ladder line is a good  
minimum.  BUT, don't get rid of your Buddipole.  It is great for Field  
Day.

Good luck and 73,

Oliver Johns - W6ODJ
