Wonder if they have any of these for 20 meters?
The wire itself is a liquid so its mechanical properties are defined by
the encasing material, which could be lots of things--a rubber band,
bathroom caulk," says Dickey. "Then the antenna is like the caulk or the
rubber band, and it snaps back."
Because the signals that antennas pick up depend on their shape, this
antenna can be tuned to a huge range of frequencies just by stretching
it. The hope is this kind of flexible, tunable antenna could be used in
flexible electronics, in biomedical devices, in military applications
and as a sensor embedded in construction materials.
