Choose the ATU-20DS if your EVX radio runs in the 440–470 MHz UHF band and you want a short, low-profile antenna. Need a longer reach?

Why Choose the ATU-20DS
UHF 440–470 MHz
Tuned for the 440–470 MHz UHF band so your EVX radio transmits and receives where it is licensed to operate.
Low-Profile 3.15 In
At just 3.15 inches, the stubby profile stays out of the way on a belt or in a chest rig — less snag, cleaner look.
Genuine-Fit Replacement
A direct EVX-series replacement antenna — thread it on and restore reception without modifying the radio.
UHF Frequency Only
Built strictly for UHF radios — pair it with a UHF EVX model, not a VHF unit, for correct performance.
Compatible Radios
