For one good version of the J-pole that is very portable see;
http://hamgate1.sunyerie.edu/~larc/pocketJpole.htm

A Google search on "twin lead J-pole" (without the quotes) will give 
you many more sites.

The J-Pole will outperform a rubber duck in nearly ALL cases.
Even the loose from the coax is offset by the added height of the
antenna.
With RG-58 coax you would need to have more coax than you want to carry
to make the j-pole less efficient than the rubber duck.

For emergency antennas I usually use RG-174 about 20' long and it is
FAR better than the rubber duck.

I use these antennas on Ham radio and marine VHF and they work very
well.
