Kenwood SKRA-15MRV2 Replacement UHF Stubby Antenna 450-470 MHz SMA Female Connector

The Kenwood SKRA-15MRV2 is an OEM replacement stubby antenna engineered for the UHF band, covering 450–470 MHz with a center frequency of 460 MHz. Its helical construction delivers a compact 75 mm profile while maintaining unity gain and omnidirectional, vertically polarized radiation — preserving the full 360-degree coverage pattern your radio was designed to provide. A VSWR of less than 2.0 across the rated band ensures efficient power transfer between radio and antenna, minimizing reflected energy and protecting the final-stage amplifier. The urethane sleeve and ABS cap provide durable, field-ready construction suited to the demanding environments where Kenwood portables are routinely deployed. The SMA Female connector provides a secure, precise-fit mechanical and electrical connection to compatible Kenwood radio models, making this a direct drop-in replacement with no adaptation required.

Key features & benefits

• UHF 450–470 MHz Coverage — Tuned to a 460 MHz center frequency, this antenna operates across the full 450–470 MHz UHF segment commonly used in business, public safety, and industrial communications, ensuring reliable on-frequency performance.
• Compact Stubby Form Factor — At 75 ± 3 mm total length, the stubby profile reduces snag risk and improves portability compared to a full-length whip, making it well suited for close-quarters work environments and vehicle operations.
• Omnidirectional Vertical Polarization — The vertically polarized, omnidirectional radiation pattern provides consistent 360-degree coverage without requiring the user to orient the radio toward a repeater or base station.
• Unity Gain Helical Design — The helical radiating element delivers unity gain, maintaining the radio's rated output effectively across the coverage area without the pattern distortion that can accompany high-gain directional elements.
• Low VSWR for Efficient Power Transfer — A VSWR of less than 2.0 minimizes reflected power back into the transmitter, protecting internal components and ensuring maximum radiated output from the host radio.
• SMA Female Connector — The SMA Female connector interface provides a solid, industry-standard mechanical connection, and is matched precisely to the antenna port on compatible Kenwood UHF portable radios.
• Durable Urethane Sleeve and ABS Cap — The urethane sleeve resists abrasion and flex fatigue during daily handling, while the ABS cap protects the radiating element tip from impact damage in the field.
