Coaxial cable are used for transmission of high frequency energy and signals with low loss and with minimal phase and amplitude distortion.
The Co-axial cable type RG were originally developed for Military applications. They meet the requirements of American Military regulation MIL-C-17, because of their internationally acclaimed constant high quality, they are today employed through out the whole field of High Frequency Technology.

Why PTFE insulation under Rf Coaxial Cables
- RF transmission equipment typically operate in hostile working condition eg satellite, radar system etc. PTFE offers unparalleled protection against the such environment.
- PTFE is one of the lowest dielectric constant and loss factor material
- Inert to practically all chemicals even at elevated temperatures
- Fire (flame) proof
- Smaller size, lighter weight and much higher reliability
- Excellent thermal stability for use from -60C to 260C.
