What is the effect of applying a light amount of grease to the tap port threads or using sealing tape at the port on a drop connection?

• A. Prevents moisture penetration
• B. Improves mechanical strength
• C. Increases electrical resistance
• D. Prevents electrical arcing

Answer: (A)

Sealing the connection helps keep moisture out where the threads meet the tap port. In a drop connection, water or humidity can seep in through those threads and cause corrosion and changes in the dielectric environment, which degrades the RF signal. A light coat of grease or sealing tape blocks that moisture path and helps maintain stable impedance, so the connection remains reliable. This isn’t about making the connection physically stronger or about changing resistance or arcing; the main benefit is moisture control to protect signal quality.
