You can use the Hustler spider attachment and put up to three coils on the
same antenna - I've seen it done with as many as five bands covered.
General rule is the higher you can get the coil the better. The down side
is the higher the coil also put the weight up high and you may need to guy
the antenna. I usually run two coils on one antenna (40 and 20) on major
trips and always guy the antenna.

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.
