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

I bought a buddipole antenna system and I want to get one of the
subject units but I don't know the difference between them, and what
each one does, and which one will help me with the setup with my K3
and my antenna system ?
When I bought my K3 I also bought a KAT3 which I believe is an
antenna tuner for the K3 -- Will this do the same thing to match the
antenna to the K3, or am I better off getting another unit like a
LDG Z-100 or an LDG AT-200 Pro or something else like one of the MFJ
units ?
Where does the "baluns" come into this play with either unit ?
I am just a Technician class and am studying for the General class
and I have not built the K3 that I have yet, and all this antenna
stuff is pretty confusing.
Can anyone help please ?
Thank you,
Paul
