VHF 148–161 MHz 7.5" Flexible Whip Antenna

The Motorola NAD6579A VHF 148–161 MHz 7.5-Inch Flexible Whip Antenna is an enhanced-performance antenna designed to provide reliable VHF transmit and receive performance for compatible Motorola portable two-way radios.

Operating across the 148–161 MHz VHF frequency range, the NAD6579A is specifically tuned for compatible radios operating within this portion of the commercial VHF band.

The antenna features a 7.5-inch (approximately 19 cm) flexible whip design, providing a longer antenna element than Motorola's standard 5.5-inch and compact stubby antenna options.

Motorola constructs the NAD6579A with a one-piece finish, steel core, and spiral-wound conductor designed to provide optimal radiation characteristics.

Its longer flexible whip construction makes the NAD6579A an excellent choice for applications where radio performance is prioritized over maintaining the smallest possible antenna profile.

The flexible design also allows the antenna to bend during normal movement, improving comfort when the portable radio is worn on a belt, carried on a vest, or used throughout an active workday.

The NAD6579A 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.

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

Enhanced-Performance 7.5-Inch Design

The NAD6579A features a:

7.5-Inch / Approximately 19 cm Flexible VHF Whip Antenna

Its longer design distinguishes the NAD6579A from Motorola's shorter 5.5-inch whip and 3.5-inch stubby antenna options.

The antenna is designed for users who prioritize antenna performance and VHF communications over maintaining the smallest possible radio profile.

The flexible construction also allows the antenna to accommodate normal movement when the radio is:

• Worn on a belt

• Carried on a work vest

• Used while walking

• Used while climbing or bending

• Carried around machinery or equipment

• Used inside vehicles

• Used throughout extended work shifts

Antenna Construction

Motorola specifies the NAD6579A with:

• One-piece finish

• Steel core

• Spiral-wound conductor

• Flexible whip construction

These design characteristics are intended to provide optimal radiation characteristics while maintaining the flexibility needed for portable-radio applications.

Important

The NAD6579A is a VHF flexible whip antenna designed for operation from:

148–161 MHz

It is not a UHF antenna.

The NAD6579A's 7.5-inch length is intentional and distinguishes it from Motorola's shorter VHF antenna options.

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.

Always verify the radio model and operating frequency before ordering.

The portable radio is not included.
