VHF 146–162 MHz 9cm Stubby Antenna

The Motorola HAD9742A VHF 146–162 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 146–162 MHz VHF frequency range, the HAD9742A is specifically tuned for compatible radios operating within this 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 traditional full-length VHF whip antennas.

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 the HAD9742 as a rugged and dependable antenna designed for years of reliable communications, making it well suited for everyday commercial and professional radio applications.

The HAD9742A 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.

The HAD9742A has been used across multiple generations of Motorola commercial portable radios.

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

Stubby Antenna Design

The HAD9742A features a:

9 cm / Approximately 3.5-Inch VHF Stubby Antenna

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

Motorola specifically describes stubby antennas as ideal when a portable radio is worn on the belt because the shorter antenna is less obtrusive.

This makes the HAD9742A 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.

Frequency-Specific Design

The HAD9742A is specifically tuned for:

146–162 MHz

This makes it a frequency-specific VHF antenna rather than a broadband antenna covering the entire commercial VHF spectrum.

For best performance, the radio's programmed frequencies should fall within the antenna's supported frequency range.

Related Motorola VHF Antennas

Motorola offers several VHF antenna options covering different portions of the VHF band:

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

• HAD9742A – VHF 146–162 MHz Stubby Antenna, 9 cm

• HAD9743A – VHF 162–174 MHz Stubby Antenna

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

• NAD6502AR – VHF 146–174 MHz Heliflex Antenna

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

Important

The HAD9742A is a VHF stubby antenna designed for operation from:

146–162 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 HAD9742A with the closely related HAD9743A:

HAD9742A = VHF 146–162 MHz 9 cm Stubby Antenna

HAD9743A = VHF 162–174 MHz Stubby Antenna

The two antennas have similar compact designs but are tuned for different portions of the VHF frequency band.

Always verify the radio model and operating frequency before ordering.

The portable radio is not included.
