Can a Coaxial Cable Be Flexible?

Yes — flexible coaxial cables are designed to balance signal transmission efficiency and mechanical flexibility.
The characteristic impedance of a typical flexible RF coaxial cable ranges between 50 and 92 ohms.

While flexible cables are ideal for short-distance, high-frequency applications, their higher attenuation limits their effective range to less than one kilometer (around half a mile) unless signal repeaters are used.
They are commonly employed in RF testing, laboratory environments, and high-frequency measurement systems that require both flexibility and performance.

Are RF Cables the Same as Coaxial Cables?

The abbreviation RF stands for Radio Frequency, which refers to any frequency within the electromagnetic spectrum used for transmitting radio waves.
When an RF current flows through an antenna, it generates an electromagnetic field capable of propagating through space — forming the basis of wireless communication technologies.

While RF cable and coaxial cable are often used interchangeably, there’s a subtle difference:

RF cables carry oscillating radio frequency signals.
Coaxial cables can carry RF as well as other signal types, depending on design.

In most modern applications, RF coaxial cables are used for both wired RF connections and testing setups, whereas wireless RF modules handle radio transmission. Understanding this distinction ensures proper component selection in communication systems and test environments.
