VHF 136–155 MHz 9cm Stubby Antenna

The Motorola PMAD4012A VHF 136–155 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 136–155 MHz VHF frequency range, the PMAD4012A is specifically tuned for compatible radios operating within the lower 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 describes this stubby antenna family as using a rugged helical design with a capless sheath for maximum flexibility, combining durability with a compact form factor suitable for everyday professional radio use.

The PMAD4012A uses a red color code to help distinguish its frequency range from other similar Motorola VHF antennas.

The PMAD4012A 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 PMAD4012A operates across:

136–155 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 CP100d

• Motorola CP200d

• Motorola CT250

• Motorola CT450

• Motorola EX500

• Motorola EX560

• Motorola EX600

• Motorola EX600 XLS

• Select additional compatible Motorola VHF portable radios

The PMAD4012A has been used across multiple generations of Motorola commercial and professional portable radios.

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

Stubby Antenna Design

The PMAD4012A 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 PMAD4012A 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 describes this antenna family as using a rugged helical construction with a capless sheath designed to provide maximum flexibility.

This construction allows the PMAD4012A to provide the required VHF antenna functionality within its compact 9 cm form factor.

Red Color Code

The PMAD4012A uses a red color code as a visual frequency-identification aid.

This helps distinguish the antenna from similar-looking Motorola VHF stubby antennas designed for different frequency ranges.

The color code does not indicate the overall antenna color; the antenna itself has the traditional black exterior used on Motorola portable-radio antennas.

Related Motorola VHF Antennas

Motorola offers several similar frequency-specific 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 Flexible Whip Antenna, 14 cm

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

Important

The PMAD4012A is a VHF stubby antenna designed for operation from:

136–155 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 PMAD4012A with the similar PMAD4013A:

PMAD4012A = VHF 136–155 MHz 9 cm Stubby Antenna – Red Color Code

PMAD4013A = VHF 155–174 MHz 9 cm Stubby Antenna – Black Color Code

Both antennas have the same compact 9 cm form factor but are tuned for different portions of the VHF frequency band.

For compatible radios operating from 136–155 MHz that require a longer antenna, Motorola also offers the PMAD4014A 14 cm flexible whip antenna.

Always verify the radio model and operating frequency before ordering.

The portable radio is not included.
