What Yokowo does

Yokowo Co., Ltd. (株式会社ヨコオ) is a Japanese antenna manufacturer founded in 1956, headquartered in Tokyo with a wholly-owned US sales and manufacturing subsidiary, Yokowo Manufacturing of America, LLC, in Hilliard, Ohio. The company designs and produces wireless antennas spanning navigation (patch and film GNSS/GPS antennas covering L1, L1/L2, L1/L5, and full-band multi-constellation including QZSS L6), data communication (LTE film antennas, 4G/5G MIMO, and compact Sub6 Local 5G MIMO antennas), and broadcast reception (DTV and European DAB film antennas). R&D is supported by proprietary electromagnetic field simulators, anechoic chambers, and five radio wave measurement sites (including two vehicle-scale chambers) used to qualify designs against automotive durability and RF performance standards.

The company's customer base spans automotive OEMs (navigation and telematics), drone/UAV manufacturers (autonomous flight positioning), vending machine operators (cashless payment and inventory connectivity), agricultural technology providers (CLAS-compatible precision positioning), and broader IoT device manufacturers. Distribution combines direct enterprise sales via the yokowo-antenna.jp inquiry system, global catalog availability through DigiKey, and a layered network of regional sales representatives and authorized distributors (Westward Sales, R.O. Whitesell and Associates, AMASCO, ETS Alliance, JW Associates) covering all US states for enterprise accounts. Pricing is quote-based and not publicly disclosed.

In 2024 Yokowo launched what it describes as the world's smallest-class compact Local 5G (Sub6) MIMO antenna, released its first GNSS antenna supporting Japan's Michibiki L6 satellite signal for centimeter-class positioning, secured design-in into a precision-agriculture work-support system, exhibited for the first time at the MSV 2024 engineering fair in the Czech Republic, and opened a dedicated DX Solutions website (yokowo-dx.com) featuring remote key access systems and an IoT platform branded 'intdash' — collectively signaling a strategic shift from passive component supply toward integrated connectivity solutions.

Core offering

Yokowo manufactures and supplies antennas and connectivity components for automotive, IoT, and wireless communication applications. The product portfolio includes GNSS/GPS patch and film antennas (L1, L1/L2, L1/L5, and full-band multi-constellation), LTE and 4G/5G MIMO data communication antennas, DTV/DAB broadcast film antennas, and compact local 5G MIMO antennas for private industrial networks. These antennas are designed for integration into vehicles, drones, vending machines, agricultural machinery, digital signage, and industrial IoT devices.

Product overview

Yokowo manufactures a broad portfolio of wireless antennas spanning three core categories: Navigation Antennas (GNSS/GPS patch and film antennas including L1, L1/L2, L1/L5, and full-band multi-constellation models), Data Communication Antennas (LTE, 4G/5G MIMO, and compact 4G/5G film antennas), and Broadcast Antennas (DTV and European DAB film antennas). It also offers a dedicated Local 5G MIMO antenna (YOZ-52714) for private/public 5G enterprise networks. All products are sold as standalone antenna modules designed for integration into IoT devices, vehicles, industrial equipment, and infrastructure. Yokowo's antenna lineup covers global navigation satellite systems (GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC) and cellular bands from LTE through 5G NR, targeting automotive manufacturers, industrial IoT integrators, and precision agriculture providers.
