Why is coaxial cable the most common feed line for amateur radio antenna systems?

• A. It is the least expensive
• B. It is easy to use and requires few special installation considerations
• C. It provides the highest signal quality
• D. It can be used at any frequency

Answer: (B)

Coaxial cable is favored as the most common feed line for amateur radio antenna systems primarily because it is easy to use and requires few special installation considerations. This ease of use stems from its design, which provides both shielding and structural integrity. The coaxial configuration—where a central conductor is surrounded by an insulating layer and an outer conductor—helps to minimize interference from external sources, making it suitable for most amateur applications. Moreover, coaxial cables do not require specialized connectors or elaborate installation techniques, making them accessible even for newcomers to amateur radio. Their flexibility and relatively lightweight nature also contribute to their popularity, allowing for simpler handling and routing in various installation environments. While cost, signal quality, and frequency capabilities are also important factors, the straightforward nature of coaxial cable makes it particularly appealing for a wide range of users in amateur radio, from those setting up basic stations to more advanced operators.
