A type of antenna that I keep packed for use at short notice is a halfwave
centre fed dipole for use as a vertical, where part of the coax feeder forms
the bottom half of the dipole. With this arrangement the coax feeder comes
away from the bottom of the antenna not from the centre, radials are not
essential and matching is easy. The complete antenna and feeder could be
made using a single length of coax. Although it is a single band antenna
there might be a modification, which I have not yet tried, to get it to work
well on two perhaps three bands. I have used this scheme to feed Half
Squares and other types of phased vertical arrays.
If of any interest to you please let me know and I will send you a diagram.

Summer is around the corner (finally here, up at the arctic circle).
Those
of you organized enough to have the K2 ready to be taken on the road or on
the trail on a short notice, what do you have in that travel kit, aside
from
the K2 itself?
CW-key, mike, headphones, log book, pre-cut antenna wire, telescoping
pole,...?
