806-941 MHz 1/4 Wave Stubby Antenna

The Motorola 8505241U06 806–941 MHz 1/4-Wave Stubby Antenna is a compact broadband antenna designed to provide reliable transmit and receive performance for compatible Motorola portable two-way radios operating in the 800 and 900 MHz bands.

Covering the broad 806–941 MHz frequency range, the 8505241U06 can support compatible Motorola radios operating in both 800 MHz and 900 MHz applications.

The antenna features a compact 1/4-wave stubby design that provides a lower-profile alternative to traditional full-length whip antennas.

Motorola specifically designed this antenna for applications where a short, non-obtrusive profile is desirable. Its compact construction makes it particularly convenient when a portable radio is worn on a belt or carried throughout an active workday.

The antenna's short profile also helps reduce the likelihood of catching or snagging on clothing, equipment, vehicle interiors, shelving, and other surrounding objects.

Motorola describes the 8505241U06 as a rugged antenna featuring a capless sheath for maximum flexibility, helping it withstand the movement and incidental contact associated with everyday professional radio use.

The 8505241U06 is an excellent 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 can vary according to radio model, frequency configuration, and antenna connector.

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

1/4-Wave Stubby Design

The 8505241U06 features a:

1/4-Wave Broadband Stubby Antenna Design

Motorola describes the antenna as short and non-obtrusive, making it particularly suitable for radios worn on a belt.

The compact configuration is convenient when the radio is:

• Worn on a belt

• Carried on a work vest

• Used inside vehicles

• Used around machinery or equipment

• Used in warehouses

• Used in public-safety or commercial environments

• Carried throughout extended work shifts

The shorter profile helps reduce interference with clothing, equipment, and surrounding objects compared with longer whip antennas.

Broadband 800/900 MHz Coverage

One of the primary advantages of the 8505241U06 is its broad:

806–941 MHz frequency range

Rather than being limited to only a narrow portion of the 800 or 900 MHz spectrum, Motorola designed this antenna for compatible applications across both bands.

This makes the 8505241U06 a versatile replacement antenna for compatible Motorola portable radios operating within its supported frequency range.

Rugged Flexible Construction

Motorola describes the 8505241U06 as a rugged antenna with a:

Capless Sheath for Maximum Flexibility

This construction allows the antenna to accommodate normal movement and incidental contact while maintaining its compact stubby form factor.

Important

The 8505241U06 is an 800/900 MHz broadband stubby antenna designed for operation from:

806–941 MHz

It is not designed for conventional VHF or UHF portable-radio applications.

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

The radio's operating frequency and antenna compatibility should both be verified before ordering.

The portable radio is not included.
