896–941 MHz 1/2-Wave Flexible Whip Antenna

The Motorola 8505241U04 896–941 MHz 1/2-Wave Flexible Whip Antenna is a high-performance replacement antenna designed for compatible Motorola portable two-way radios operating in the 900 MHz frequency band.

Operating across the 896–941 MHz frequency range, the 8505241U04 is specifically designed for compatible radios operating within this portion of the 900 MHz band.

The antenna features a 7-inch 1/2-wave flexible whip design, providing a longer antenna profile than Motorola's compact stubby alternatives.

Motorola constructs the 8505241U04 with a one-piece finish, steel core, and spiral-wound conductor designed to provide optimal radiation characteristics.

The flexible whip construction allows the antenna to bend during normal movement, helping improve comfort when the portable radio is worn on a belt or carried throughout an active workday.

For users who prioritize radio performance over maintaining the smallest possible antenna profile, the 8505241U04 provides an excellent alternative to a shorter stubby antenna.

The 8505241U04 is an ideal replacement for a lost, damaged, bent, or worn original antenna and can also be kept as a spare for organizations maintaining fleets of compatible Motorola portable radios.

Compatibility varies by radio model, frequency configuration, and antenna connection.

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

1/2-Wave Flexible Whip Design

The 8505241U04 features a:

7-Inch 1/2-Wave Flexible Whip Antenna

Unlike a compact stubby antenna, the 8505241U04 uses a longer whip-style design.

Motorola specifically constructs the antenna with a steel core and spiral-wound conductor to provide optimal radiation characteristics.

Its flexible construction makes the antenna suitable when the radio is:

• Worn on a belt

• Carried on a work vest

• Used while walking

• Used around machinery or equipment

• Carried inside vehicles

• Used throughout extended work shifts

The flexible design allows the antenna to accommodate normal movement while maintaining its full-length whip configuration.

Antenna Construction

Motorola specifies the 8505241U04 with:

• One-piece finish

• Steel core

• Spiral-wound conductor

• Flexible whip construction

• 1/2-wave antenna design

These characteristics provide a durable antenna designed for dependable 900 MHz portable-radio communications.

Whip vs. Stubby Antenna

The 8505241U04 provides a longer antenna option than Motorola's 8505241U06 stubby antenna.

8505241U04 = 896–941 MHz 1/2-Wave Flexible Whip Antenna

8505241U06 = 806–941 MHz 1/4-Wave Broadband Stubby Antenna

The 8505241U04 is approximately 7 inches long and is designed for users who prefer a full-size flexible whip antenna.

The 8505241U06 provides a much shorter profile and broader 800/900 MHz coverage for applications where compact size is preferred.

Important

The 8505241U04 is a 1/2-wave flexible whip antenna designed for operation from:

896–941 MHz

It is not a VHF or conventional UHF antenna.

Do not select an antenna based solely on physical fit. Portable-radio antennas are designed for specific frequency ranges and radio platforms.

Do not confuse the 8505241U04 with the similar 8505241U06:

8505241U04 = 896–941 MHz, 1/2-Wave Flexible Whip, 7 Inches

8505241U06 = 806–941 MHz, 1/4-Wave Broadband Stubby

Always verify the radio model and operating frequency before ordering.

The portable radio is not included.
