Q

What type of coaxial cable would be most appropriate for a long transmission line run?

🔍 Key Concepts

• Signal loss (attenuation) vs. cable length in VHF/UHF coaxial cables • How cable diameter and construction affect resistance and loss • Typical uses of RG-58, RG-59, RG-8, and RG-174 on marine or radio installations

💭 Think About

• Which of these cable types is known for lower loss over long distances and is commonly used for higher power or longer RF runs? • Compare which options are thinner, more flexible, or meant for short jumpers versus which are thicker and better for long main runs. • Think about what a long transmission line on a vessel or radio tower would generally require in terms of signal strength at the far end.

✅ Before You Answer

• Verify which cable type has the lowest attenuation per foot at VHF frequencies among the choices. • Check which of these is commonly recommended as the main feed line from a radio to an antenna for longer distances, not just short patch cables. • Make sure you are not choosing a cable just because it is more flexible or smaller, but because it is better for long-distance RF transmission.
