PORTABLE ANTENNA, ATU-6DS, 450-485 MHZ, 450–485 MHz UHF Antenna

Motorola AAE20X503 ATU-6DS UHF Stubby Antenna – 450–485 MHz

The Motorola AAE20X503 ATU-6DS UHF Stubby Antenna is a compact replacement antenna designed for compatible Motorola and Vertex Standard portable two-way radios operating in the 450–485 MHz UHF frequency range.

Its short, low-profile design makes it ideal for users who wear their radio on a belt or carry it throughout the workday. Compared with a full-length whip antenna, the stubby design helps reduce snagging and keeps the radio more compact while maintaining reliable communication within its specified frequency range.

The AAE20X503 is well suited for commercial, industrial, security, hospitality, maintenance, and other professional two-way radio applications requiring a durable UHF portable radio antenna.
