Motorola PMAD4117A VHF Helical Antenna 136-155MHz XPR3300 XPR3500 XPR7550

The Motorola PMAD4117A is an OEM VHF/GPS combination helical antenna engineered for MOTOTRBO portable radios operating in the 136–155 MHz frequency band. Designed as a direct factory replacement, it delivers reliable VHF signal performance across professional land-mobile radio deployments in public safety, utilities, hospitality, and commercial enterprise environments. The integrated GPS receive element allows GPS-capable MOTOTRBO radios to leverage location services through a single antenna connection, eliminating the need for a separate GPS accessory. Radios in the XPR 3000 series that lack onboard GPS hardware still accept and benefit from this antenna for VHF communications. Its helical winding provides a compact, low-profile form factor compared to a full-length whip while maintaining robust field durability for day-to-day professional use.

Key features & benefits

• VHF/GPS Combination Design — Supports both VHF voice communications in the 136–155 MHz range and GPS signal reception in a single antenna element, enabling location services on GPS-capable MOTOTRBO radios without any additional hardware.
• 136–155 MHz Optimized Tuning — Factory-tuned to the 136–155 MHz VHF sub-band, ensuring maximum radiated efficiency and receive sensitivity for radios programmed within this range — a common segment for public safety, government, and industrial licensees.
• Helical Form Factor — The helical winding reduces overall antenna length relative to a quarter-wave whip, making it more resistant to snagging and breakage in demanding field environments while remaining easy to carry and store.
• Genuine Motorola OEM Part — Manufactured and quality-verified by Motorola Solutions to meet the same performance and durability standards as the antenna shipped with new MOTOTRBO radios, ensuring full factory compatibility and no degradation of radio system performance.
• Broad MOTOTRBO Platform Compatibility — Officially listed as a compatible accessory for the XPR 3300, XPR 3500, XPR 3500e, XPR 7350, XPR 7350e, XPR 7550, and XPR 7550e portable radios, covering both mid-tier and premium MOTOTRBO product lines.
• Drop-in Replacement Convenience — Matches the OEM antenna connector interface of supported MOTOTRBO portables, enabling field technicians and system administrators to replace worn or damaged antennas quickly without tools or radio re-programming.
