While RG-178's compact size offers advantages in confined spaces, it is important to note that its higher signal attenuation compared to larger cables may limit its effectiveness over longer distances. Additionally, the thinner shielding can make it more susceptible to electromagnetic interference, which should be considered when designing communication systems.
