1. A coaxial video push-cable, comprising:
a central structural element of dielectric material selected to have a predefined elastic modulus;
a conductor layer disposed about the central structural element;
an impedance tuning layer disposed about the conductor layer, comprising a dielectric material having a thickness selected to provide a predefined electromagnetic impedance;
a shielding layer disposed about the impedance tuning layer; and
a jacket enclosing the shielding layer, impedance tuning layer, conductor layer, and central structural element.
