The answer depends on a lot of things -- your technical background, your
operating style and objectives, etc. What do you plan to do with your
"portable" station? Backpacking? Driving somewhere to set up? In the
wilderness or in a neighborhood park? What do you want to work? What
bands, what style? Contesting, summits, lighthouses, casual operation,
vacations, etc.?
Definitely do NOT waste money on an antenna analyzer until you have real
antennas to measure. Besides -- the KX3 has a very good SWR readout
built in, so it's easy to use to figure out where your antenna is
resonant, and tweak it to length if necessary. If the feedline is short,
all you really care about is whether the antenna loads -- push the
button to activate the KXAT3 and see if it loads OK (close to full power).
The PX3 is VERY useful when trying to find activity on a quiet band, but
you must learn to use it first.
I agree with the suggestion of some form of launcher to get wires in
trees. The tennis ball launcher is great if you're driving to the site,
but far too heavy to carry up a trail. For backpacking, something like a
"wrist rocket" would be a far better choice. Several of my local friends
(AE6RF and N6RNO) are quite skilled at launching wires into trees using
nothing more than fishing line with a small heavy weight attached, using
their arm as a catapault. Once the line is in the tree, use it to pull
up the rope that will hold the antenna.
I'm not a fan of Buddipoles -- inefficient, heavy, expensive. I like one
of several telescoping fiberglass poles to which it's easy to tape a
wire. Buy or improvise one or more fixtures to mount it vertically, buy
more wire to use as radials or a counterpoise, and you've got a far more
effective antenna for less money. #18 (or even #22) works fine for
backpacking.
