Kenwood KRA-27M Portable Helical UHF 440-490 MHz Antenna SMAFemale Connector

The Kenwood KRA-27M is the standard-length UHF whip antenna for the KRA-27 antenna family, purpose-built for Kenwood portable two-way radios operating in the 440–490 MHz UHF band. At 150 mm (5.90 in) in length, it provides the signal coverage and radiation pattern expected from a full-size whip element — an appropriate choice for field personnel who require consistent link margin without resorting to a shorter stubby or low-profile helical design. The SMA Female connector mates directly with the radio body, eliminating adapters and maintaining a secure, low-loss interface in demanding environments. As an OEM Kenwood replacement and upgrade antenna, the KRA-27M is the factory-matched option for professional LMR users across public safety, security, facilities management, and commercial operations who depend on Kenwood NX-series and TK-series portables.

Key features & benefits

• 440–490 MHz UHF Coverage — Tuned specifically to the 440–490 MHz UHF segment — the most common commercial LMR UHF band in North America — ensuring the antenna resonates at the intended operating frequencies of compatible Kenwood portables rather than being a broadband compromise.
• Standard-Length Whip Construction — At 150 mm (5.90 in), the KRA-27M is Kenwood's full standard-size UHF whip, offering superior radiation efficiency and range compared to stubby or low-profile helical alternatives, making it the preferred choice when maximum link margin is the priority.
• SMA Female Connector Interface — Equipped with an SMA Female connector that mates directly and securely to the SMA Male port on compatible Kenwood portable radios, providing a robust, low-loss RF connection with no adapters required.
• Unity Gain Radiator — Rated at unitary (0 dBd) gain — the correct design target for a portable whip operating against the user's body — delivering omnidirectional coverage in the horizontal plane and reliable performance across diverse terrain and building environments.
• Broad NX-Series and TK-Series Compatibility — Verified by Kenwood documentation and authorized distributor data as compatible with a wide portfolio of Kenwood portable radios spanning the TK-3000, TK-3402, TK-3312, NX-300, NX-305, NX-340, NX-1300, NX-3300, NX-3320, NX-5300, and TKD-340 — covering both analog FM and NXDN/DMR digital platforms.
• OEM Kenwood Replacement Part — Manufactured and supplied by Kenwood as an official accessory for its LMR portable radio lineup, ensuring full dimensional compatibility with the radio housing, correct torque specification on the SMA connector, and consistent RF performance matching factory antenna parameters.
