True or False? If you are using multiple power Tees, the Shield / Drain connection should be connected to the non-current carrying RF Ground system at only one location.

True or False? If you are using multiple power Tees, the Shield / Drain connection should be connected to the non-current carrying RF Ground system at only one location.

• A. True
• B. False
• C. Not specified
• D. It should be connected at every tee

Answer: (A)

When shielding is used with multiple power tees, the drain should be tied to the RF ground at a single point. This single-point connection prevents RF currents from circulating along the shield, which would otherwise occur if the shield were connected at several locations. Ground loops along the shield can inject noise and degrade shielding effectiveness, defeating the purpose of the shield. By linking the shield to the non-current carrying RF ground system in one place, you provide a quiet, stable reference for the RF path while allowing the power ground to carry its currents separately. Connecting at every tee or not specifying a location would introduce unwanted current paths and potential EMI, so the single-point connection is the correct practice.
