Motorola PMAD4118 Antenna VHF/GPS 152-174 Mhz XPR 3300 XPR 3500 XPR 7550

The Motorola PMAD4118 is a genuine OEM VHF/GPS helical antenna engineered for MOTOTRBO portable radios operating across the 152–174 MHz VHF frequency band. Its helical construction delivers a compact, low-profile form factor that holds up to the demands of daily professional use in public safety, logistics, manufacturing, and field operations. The dual-function VHF/GPS design allows compatible GPS-enabled radios to leverage location services through a single antenna element, reducing connector wear and simplifying the radio's profile. For XPR 3000 series radios that do not include GPS capability, the antenna still provides full VHF performance. As a genuine Motorola accessory, the PMAD4118 is built to the same tolerances as the original equipment, ensuring consistent RF performance and a secure, reliable fit across the broad range of compatible MOTOTRBO DP, XiR, R7, and XPR series handhelds.

Key features & benefits
