A hallway patch antenna is specified for a clinic corridor. What does passive antenna gain mean in that design?
Select an answer to reveal the explanation.
Short Explanation
A patch does not drink PoE to yell louder — it shapes the shout down the hallway. Passive gain is focus, not a tiny booster amp hiding in the plastic. Pattern tradeoffs are the whole point of that corridor antenna.
Full Explanation
Passive antenna gain results from focusing RF energy into a preferred pattern through antenna geometry and directivity rather than from an active powered amplifier stage. A hallway patch typically concentrates energy along the corridor while reducing it elsewhere. Passive gain is a physical antenna property, not a controller software toggle, and it does not create isotropic "more everywhere" power. Technicians should install the specified antenna knowing coverage shape changes with gain and pattern.
