A rubber duck antenna is a flexible, helical antenna encased in a rubber or plastic sheath for durability and protection. Instead of a straight metal rod, it uses a coiled wire to reduce its physical length while maintaining electrical performance. This design allows it to be compact, rugged, and resistant to damage from bending or impact.
Typical Use: Handheld radios (walkie-talkies), scanners, and portable transceivers
Frequency Range: Commonly VHF (Very High Frequency) and UHF (Ultra High Frequency)
Advantages: Compact, flexible, durable
Disadvantages: Lower efficiency and gain compared to full-sized antennas
