RG-178 is a type of RF coaxial cable that is commonly used in telecommunications and radio frequency transmission requiring a high operating temperature. This cable is characterised by its small diameter and flexibility, making it suitable for applications where space is limited. However, due to its small size, RG-178 has a higher signal loss compared to larger cables, which can limit its effectiveness over longer distances. Its thin shielding can make it more susceptible to interference. While RG-178 is a practical choice for compact installations and short-range applications, it may not be the optimal choice for larger, more complex systems or environments with high levels of interference.
