Coaxial cable, or coax (pronounced), is a type of cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield.

Many coaxial cables also have an insulating outer sheath or jacket.

The term coaxial comes from the inner conductor and the outer shield sharing a geometric axis.

Coaxial cable was invented by English engineer and mathematician Oliver Heaviside, who patented the design in 1880.

Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; with frequencies between and.

Different sources define different frequency ranges as microwaves; the above broad definition includes both UHF and EHF (millimeter wave) bands.

A more common definition in radio engineering is the range between 1 and 100 GHz (300 and 3 mm).

In all cases, microwaves include the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum.

Frequencies in the microwave range are often referred to by their IEEE radar band designations: S, C, X, Ku, K, or Ka band, or by similar NATO or EU designations.

A cable is two or more wires running side by side and bonded, twisted, or braided together to form a single assembly.

The term originally referred to a nautical line of specific length where multiple ropes, each laid clockwise, are then laid together anti-clockwise and shackled to produce a strong thick line, resistant to water absorption, that was used to anchor large ships.

In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a modulating signal that typically contains information to be transmitted.

Most radio systems in the 20th century used frequency modulation (FM) or amplitude modulation (AM) to make the carrier carry the radio broadcast.

An attenuator is an electronic device that reduces the power of a signal without appreciably distorting its waveform.
