VHF 155–174 MHz 9cm Stubby Antenna

The Motorola PMAD4013A VHF 155–174 MHz Stubby Antenna is a compact replacement antenna designed to provide reliable VHF transmit and receive performance for compatible Motorola portable two-way radios.

Operating across the 155–174 MHz VHF frequency range, the PMAD4013A is specifically tuned for compatible radios operating within the upper portion of the commercial VHF band.

The antenna features a compact 9 cm (approximately 3.5-inch) stubby design, providing a lower-profile alternative to a traditional full-length whip antenna.

Its short, non-obtrusive construction makes the radio more comfortable and convenient to carry, particularly when worn on a belt. The compact profile also helps reduce the likelihood of the antenna catching on clothing, equipment, shelving, vehicle interiors, or other surrounding objects.

Motorola's stubby antennas feature a rugged helical construction with a capless sheath designed for maximum flexibility, combining a compact profile with durability suitable for everyday professional radio use.

The PMAD4013A is an excellent replacement for a lost, damaged, bent, or worn original antenna and can also be kept as a spare for businesses and organizations maintaining fleets of compatible Motorola portable radios.

Frequency Range

The PMAD4013A operates across:

155–174 MHz

This places the antenna within the VHF frequency band.

The antenna should only be used with compatible VHF portable radios operating within the supported frequency range.

Compatible Radios

Motorola-documented applications include:

• Motorola CT250

• Motorola CT450

• Motorola EX500

• Motorola EX600

• Motorola EX600 XLS

• Motorola GP328 Series

• Motorola GP338 Series

• Motorola GP329 Series

• Motorola GP339 Series

• Select additional compatible Motorola VHF portable radios

The PMAD4013A has been used across multiple generations of Motorola commercial and professional VHF portable radios.

Always verify both the portable radio model and programmed operating frequency before ordering an antenna.

Stubby Antenna Design

The PMAD4013A features a:

9 cm / Approximately 3.5-Inch VHF Stubby Antenna

The compact configuration provides a lower-profile alternative to a traditional whip antenna.

This makes the PMAD4013A particularly convenient when the radio is:

• Worn on a belt

• Carried on a work vest

• Used in warehouses or retail environments

• Used around machinery or equipment

• Carried inside vehicles

• Used in confined spaces

• Carried throughout extended work shifts

The shorter profile helps reduce the likelihood of the antenna catching on clothing, equipment, shelving, or surrounding objects.

Rugged Helical Construction

Motorola's stubby antenna design uses a rugged helical construction with a capless sheath that provides flexibility during normal portable-radio use.

This construction allows the PMAD4013A to provide the required VHF antenna functionality within a compact 9 cm form factor.

Related Motorola VHF Antennas

Motorola offers several similar VHF antenna options:

• PMAD4012A – VHF 136–155 MHz Stubby Antenna, 9 cm

• PMAD4025A – VHF 150–161 MHz Stubby Antenna, 9 cm

• PMAD4013A – VHF 155–174 MHz Stubby Antenna, 9 cm

• PMAD4014A – VHF 136–155 MHz Flexible Whip Antenna, 14 cm

• PMAD4015A – VHF 155–174 MHz Whip Antenna, 14 cm

Selecting the correct antenna depends on both the portable radio model and its operating frequency range.

Important

The PMAD4013A is a VHF stubby antenna designed for operation from:

155–174 MHz

It is not a UHF antenna.

Do not select a portable radio antenna based solely on physical fit. Antennas are tuned for specific frequency ranges, and the antenna should match both the radio platform and its programmed operating frequencies.

Do not confuse the PMAD4013A with the similar PMAD4012A:

PMAD4012A = VHF 136–155 MHz 9 cm Stubby Antenna

PMAD4013A = VHF 155–174 MHz 9 cm Stubby Antenna

For customers who need a longer antenna in the same 155–174 MHz frequency range, Motorola also offers the PMAD4015A whip antenna.

Always verify the radio model and operating frequency before ordering.

The portable radio is not included.
