Why should coax connectors exposed to the weather be sealed against water intrusion?

• A. To prevent an increase in feedline loss
• B. To prevent interference to telephones
• C. To keep the jacket from becoming loose
• D. All of these choices are correct

Answer: (A)

Sealing coax connectors that are exposed to the weather against water intrusion is primarily crucial to prevent an increase in feedline loss. When moisture enters the coaxial cable and connectors, it can lead to signal degradation and increased loss due to the corrosive effects of water and the potential for creating a short circuit. This degradation negatively impacts the signal quality and strength, which is particularly important in radio communications. Ensuring that these connectors are well-sealed helps maintain the integrity of the feedline and ensures optimal performance. While interference to telephones and issues with the jacket becoming loose are valid concerns in different contexts, the most critical reason for sealing connectors in this specific scenario primarily revolves around maintaining signal quality and minimizing loss due to environmental factors.
