Compact UHF Antenna

The PMAE4091A is designed for users who need a low-profile antenna that integrates closely with the SL-Series radio housing. Its compact shape keeps the radio comfortable to carry in a pocket, holster or on a belt.

Tuned for 450–490 MHz

This antenna kit is specifically designed for compatible UHF radios operating within the 450–490 MHz range.

Using an antenna matched to the radio’s programmed frequencies helps support efficient transmission and reception. This kit should not be installed on VHF, 800/900 MHz or incompatible UHF radio configurations.

Compatible Radios

The PMAE4091A is compatible with select Motorola radios, including:

• Motorola MOTOTRBO SL7550

• Motorola MOTOTRBO SL7550e

• Select regional SL4000 and SL4000e configurations

• Select SL 7000-Series radios operating from 450–490 MHz

Compatibility depends on the radio’s exact frequency band and housing. Confirm the complete radio model and programmed frequency range before ordering.

Replacement Antenna Kit

Unlike a standard threaded whip antenna, the PMAE4091A is supplied as a replacement kit for the SL-Series fixed antenna assembly.

The kit includes:

• UHF stubby antenna

• Retaining mini-screw

• Installation plug or retaining component

Small hardware should be handled carefully during installation to prevent loss or damage.

Fixed-Mount Installation

Installation requires securing the replacement antenna to the radio using the supplied retaining hardware.

Professional installation is recommended when:

• The existing antenna is broken inside the housing

• The retaining screw is damaged

• The antenna mount is loose

• The radio housing shows signs of impact damage

• The correct installation procedure is uncertain

Turn off the radio before removing or installing antenna components.

Choosing the Correct Frequency Split

Motorola offers similar-looking SL-Series antenna kits covering different UHF frequency ranges:

• PMAE4078: 403–425 MHz

• PMAE4076: 420–445 MHz

• PMAE4077: 438–470 MHz

• PMAE4091A: 450–490 MHz

• PMAE4092A: 480–527 MHz

Check the radio’s programmed operating frequencies before selecting an antenna kit. Where frequency ranges overlap, use the antenna recommended for the radio’s specific factory configuration.

Confirm current revision compatibility if an exact suffix is required for an existing radio fleet or purchasing contract.

Important Frequency Information

The radio model alone does not determine antenna compatibility. Before ordering, verify:

• The radio’s complete model number

• The radio’s programmed operating frequencies

• The existing antenna type

• The required antenna frequency split

Installing an antenna designed for the wrong frequency range may reduce radio performance and place unnecessary stress on the transmitter.

When to Replace the Antenna

Replacement may be necessary if the existing antenna is:

• Cracked or physically damaged

• Loose inside the radio housing

• Missing its retaining hardware

• Producing reduced or intermittent performance

• Damaged during impact or servicing

• Missing from the radio

Inspect the antenna mounting area for damage before installing the replacement kit.

Ideal Applications

• Hospitality operations

• Retail environments

• Security teams

• Schools and campus operations

• Manufacturing facilities

• Transportation and logistics

• Commercial UHF communication systems

• SL-Series fleet maintenance
