If you want something reasonably portable that will deploy quickly, you
might consider the EFHW vertical antenna from the Emergency Amateur
Radio Club in Hawaii:

You can buy some or all of the parts needed from the club, and the cost
includes Priority Mail shipping.
The complete parts list an instructions are in the PDF file if you want
to roll your own.
I hate radials, so this turned out to be a great antenna. None required!
You can hang it in a tree, or mount it on something like a 33-foot
Jackite Pole.
I've lost the source, but there is a video on YouTube that shows a ham
in New York setting one up in an old umbrella stand on his deck.
Check this out, also:

Convenient low gain options: Long-wires are easy, cheap, and wonderful.
Kites, balloons, weights tossed into tree limbs with fishing line, dangling
down the side of buildings, etc. Push-up verticals are great too, but they
need a counter poise of some sort (for the other half of the antenna... as
it were), so include at least 3 radials (three obviously because they will
be elevated... not dug into the ground for portable ops).
Convenient portable gain options: 30-6 meters...Superantenna YP3 and
portable tower is very worthy trapped beam antenna (I use this on dxpedition
every year with amazing success), Spider beams, other wire beams that are
simple to assemble... like wire verticals or delta loops. All excellent
choices... There are many antennas in the category that others will fill in
as favorites.
