Question 1 of 27070

When passing through areas of static charge, high voltages can accumulate on antennas which are insulated from ground. What protects a connected receiver from damage?

🔍 Key Concepts

• Static charge buildup on insulated antennas and its effect on receiver front ends • How receiver input stages (first RF amplifier or mixer) can be damaged by high voltage or discharge • Typical protection methods used in radio equipment (arresters, diodes, static drains)

💭 Think About

• Think about which device or circuit is placed right at the receiver input to clamp or limit voltage before it reaches sensitive components. • Ask yourself which option describes a protection method that works continuously with very fast response, even for relatively small static discharges, not just large lightning surges. • Consider which answers describe general surge/lightning protection versus what is normally built directly into the receiver circuitry itself.

✅ Before You Answer

• Verify which option specifically mentions receiver input rather than general antenna or feedline protection. • Check which devices are designed to conduct or clamp when voltage exceeds a small threshold, protecting delicate semiconductor junctions. • Confirm that the method chosen is commonly used inside electronic equipment rather than only as an external installation accessory.
