COAX Cables
Coaxial cable is a shielded one-conductor cable with the conductor embedded in a di-electricum, which is wrapped in foil or a braided shield. It is called coaxial because it includes one physical channel that carries the signal, surrounded by a layer of insulation and by another concentric physical channel, both running along the same axis.
Some of the newer cables for wireless systems (50 Ohms):
AIRCELL 7
AIRCELL 7 is a 7mm low loss extra flexible cable. It is excellent for HF operation and usable up into the microwave region. This cable has a flexible stranded center conductor, surrounded by gas injected PE foam. The UV-protecting outer jacket is made of PVC.

ECOFLEX 10
ECOFLEX 10 is a highly flexible 10 mm coaxial cable for use in the frequency range up to 4 GHz. It has a stranded centre conductor, formed by 7 pure copper wires and a PE-LLC dielectric. The EMI screening immunity of > 85 db @1 GHz is achieved through double shielding by the use an overlapping PE- stabilized copperfoil and a copperbraid with 72% coverage.
