Hi Ci,
Operating at 4 watts with a short antenna is a challenge (and "loads"
o' fun, pun intended). You'll want to use the most efficient antenna
that will fit on your vehicle. The longer the better. I've had
excellent results with QRP using an 8' ham-stick on 40-10 meters. This
is mostly due to the length. The loading coil is distributed over about
half the antenna's length, too, an improvement over a small coil at the
base.
With all such antennas you have to switch elements to change bands. A
long whip with a large motorized coil is the best way to go if you want
to avoid this hassle. Or, you can put an ATU like our new T1 at the
base of the whip.
You may also be able to tune the antenna on multiple bands with an
in-the-rig ATU, such as the KXAT1. Efficiency will probably be worse
the farther you go from the whip's resonant band.
