Smiley Antenna 5/8 Wave Slim Duck UHF Antenna – 460 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 handheld radio performance, improved range, and reliable communications when it matters most. Delivering a true omni-directional 6 dBd gain pattern, it provides a substantial performance upgrade over most stock antennas.
Precision tuned to 460 MHz with approximately ±10 MHz usable bandwidth (450–470 MHz), this antenna is designed to maintain low SWR, strong signal transfer, and consistent real-world performance throughout the UHF business and GMRS spectrum. Every antenna is individually hand-tuned and impedance matched specifically for handheld radio operation.
The 460 MHz range is commonly used for:
• GMRS communications
• Business and industrial radio systems
• Event coordination and security operations
• Hospitality and commercial communications
• Construction and manufacturing facilities
• Public service and utility communications
• Scanner monitoring where permitted by law
The compact 4-inch design utilizes a flexible base-loaded matching network and is sealed in durable synthetic rubber with a one-piece NT-MIL protective covering. Built for demanding environments, it offers excellent durability without sacrificing performance.
A Great Scanner Antenna for Racing Fans
This antenna is also an excellent choice for scanner enthusiasts monitoring UHF race communications at major motorsports events such as the Indianapolis 500, NASCAR races, IMSA events, dirt track racing, drag racing, and other motorsports where UHF communications are commonly used. The higher gain and efficient design can provide improved reception compared to many factory scanner antennas.
