Key Selling Points
- Wide Band Coverage — No Tuning Needed Covering 440–480 MHz with a 40 MHz bandwidth, the UH-417SB eliminates the need for frequency-specific tuning. Just mount it and transmit across the entire UHF band with confidence.
- High Gain for Superior Range With 6.5 dBi of gain (with ground plane) and a 5/8 over 1/2 wave design, this antenna pushes your signal farther and clearer than standard mobile antennas — ideal for hillside, urban, and open-terrain environments.
- Premium Build Quality Features a 17-7PH stainless steel whip, solid brass bushing and ferrule in a sleek black finish, gold-plated spring contact, and a stainless steel shock spring — all engineered for long-term durability and corrosion resistance in demanding field conditions.
- Low VSWR for Clean, Efficient Transmission With a VSWR of less than 1.7 and a 50-ohm impedance, the UH-417SB minimizes reflected power, protecting your radio and maximizing transmission efficiency.
- High Power Handling Rated at 160W power capacity, this antenna handles serious output power — making it suitable for both casual ham use and demanding communications applications.
- Easy NMO Mounting The NMO connection makes installation straightforward and compatible with a wide variety of mobile mounts — a standard trusted by professionals and hobbyists alike.
- Compact Yet Effective At just 79 cm in length, the UH-417SB balances a low-profile vehicle footprint with the performance of a full-sized mobile antenna.
