Smiley Antenna 5/8 Wave Slim Duck UHF Antenna – 465 MHz | 6 dBd Gain | 4” | Made in USA
Built by Smiley Antenna Co., Inc. (Est. 1984), this 5/8 Wave Slim Duck UHF antenna is engineered for maximum performance, better range, and real-world reliability on handheld radios. Delivering true omni-directional 6 dBd gain, it provides a significant upgrade over standard antennas.
Precision tuned to 465 MHz with a ±5 MHz bandwidth (460–470 MHz), this antenna maintains low SWR and consistent performance across the full range. Each antenna is impedance matched for handheld radios, not generic tuned, ensuring maximum efficiency where it matters most.
Designed with a flexible base-loaded coil matching network and sealed in synthetic rubber with a one-piece NT-MIL covering, it is strong, flexible, and built for demanding environments. At 4 inches, it delivers high performance in a compact, rugged design.
✔ Higher gain for improved range
✔ Reliable signal when it matters most
✔ Compact size with strong performance
✔ Built for real-world field use
✔ Hand-tuned in the USA
Smiley Antenna – Built, tuned, and trusted since 1984.
“Short size. Long range performance.”
