My portable antenna kit is 25' of RG-174 coax with a center
insulator on one end, and sets of dipole wires for all bands
of interest. To operate I decide which bands I want to
use, attach the appropriate wires to the coax, and string
it up in a convenient tree, on the roof, or whatever is
handy. The whole antenna kit fits in a 5" x 3" x 2" belt
pouch with room to spare for the mic, key, cables, rope, etc.
And I leave the tuner home.
Versatile, efficient, and the total cost was $10 or so.
This may not be the best for use from a motel, but if you
are planning to take a tuner along anyway you can use the
wires in other configurations - long wire, loop, etc. (I've
even used the low band dipoles to make a balanced feedline
when I could get the 20m dipole up higher than my coax
would reach.) Improvisation is the name of the game.
The drug stores sell convenient dispenser packages of string
for tying up antenna wires, complete with a built-in cutter.
They call it "dental floss".
