Abstract
Coaxial video push-cables are disclosed. One embodiment includes a central conductor and a multi-dielectric stack of multiple concentric tubular layers disposed around the central conductor having one or more structural layers and one or more impedance tuning layers where the thickness of materials of each layer are selected to provide a pre-defined elastic modulus and electromagnetic impedance, an electromagnetic shielding layer, and a jacket enclosing the shielding layer, multi-dielectric stack layers, and central conductor.

A jetter video push-cable, comprising:
- a central hose having a channel to transmit and dispense pressurized water;
- a tubular conductor layer disposed about the central hose;
- an impedance tuning layer disposed about the central hose having a thickness of a material selected to provide a predefined electromagnetic impedance;
- a shielding layer disposed about impedance tuning layer, wherein the impedance tuning layer is a multi-dielectric stack comprising multiple hollow tube layers having one or more structural layers and impedance tuning layers, wherein the layers in combination have thicknesses selected to have a predefined elastic modulus and electromagnetic impedance;
- and
- an outer jacket enclosing the outer shield layer, impedance tuning layer, conductor layer, and central hose.
