Mag One VHF 150–174 MHz Stubby Antenna

The Motorola PMAD4051AR Mag One VHF 150–174 MHz Stubby Antenna is a compact replacement antenna designed for compatible Motorola Mag One portable two-way radios.

Operating across the 150–174 MHz VHF frequency range, the PMAD4051AR is specifically designed for compatible radios operating within the upper portion of the commercial VHF band.

The stubby antenna design provides a compact alternative to longer traditional whip antennas while maintaining the antenna functionality required for everyday two-way radio communications.

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

Motorola specifically identifies the PMAD4051AR as a Mag One VHF stubby antenna and documents it as an antenna option for the Motorola Mag One BPR40 portable radio.

The PMAD4051AR is part of Motorola's Mag One accessory family, providing a cost-effective genuine Motorola replacement antenna for compatible portable radios.

It 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 radios.

Frequency Range

The PMAD4051AR operates across:

150–174 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 compatibility includes:

• Motorola Mag One BPR40 VHF

Additional established applications include:

• Motorola Mag One BPR20 VHF

• Motorola Mag One A8 VHF

The PMAD4051AR is particularly associated with the BPR40 platform and is used as the standard antenna for compatible VHF versions of the radio.

Always verify both the radio model and operating frequency before ordering a replacement antenna.

Stubby Antenna Design

The PMAD4051AR features a:

Compact VHF Stubby Antenna Design

Motorola describes its stubby antennas as non-obtrusive and particularly suitable for radios worn on a belt.

The compact configuration makes the PMAD4051AR 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 interference with clothing, equipment, and surrounding objects during normal use.

Mag One BPR40 Application

The PMAD4051AR is the VHF antenna option for the Motorola Mag One BPR40.

The BPR40 was available in both VHF and UHF configurations:

• PMAD4051AR – Mag One VHF 150–174 MHz Stubby Antenna

• PMAE4020AR – Mag One UHF 450–470 MHz Stubby Antenna

The correct antenna should be selected according to the frequency band of the BPR40 radio.

Important

The PMAD4051AR is a VHF stubby antenna designed for operation from:

150–174 MHz

It is not a UHF antenna.

Do not confuse the PMAD4051AR with the PMAE4020AR:

PMAD4051AR = VHF 150–174 MHz Stubby Antenna

PMAE4020AR = UHF 450–470 MHz Stubby Antenna

Both antennas are associated with the Motorola Mag One BPR40 platform, but they are designed for different frequency bands.

Do not select a portable radio antenna based solely on physical fit. The antenna must match both the radio platform and its operating frequency range.

Always verify the radio model and programmed frequency before ordering.

The portable radio is not included.
