Motorola TRAB4503 Phantom Omni Antenna 450-470MHz NMO Mount Ground Plane Required Compatible with All Motorola NMO Mount Radios
The Motorola TRAB4503 is a high-performance, low-profile phantom antenna engineered for ultra-rugged field conditions. Designed to operate in the 450–470 MHz UHF frequency range, this black NMO-mounted antenna delivers up to 3 dBi of gain while maintaining a compact, whipless form factor. Built using TE Connectivity's patented Phantom® design, the antenna is ideal for applications where discretion, durability, and performance are essential—such as public safety, fleet, or utility environments.
This model requires a metallic ground plane and is compatible with all Motorola radios that support standard NMO-style mounts. It is particularly valued for its field diversity, low angle radiation pattern, and resistance to damage from car washes, trees, and vandalism.
