Description
Daiwa specializes in amateur radio station accessories and measurement equipment. Unlike manufacturers that focus on transceivers, Daiwa’s product line centers on equipment used to monitor, control, and optimize radio station performance.
The company’s best-known products are its SWR and power meters, many of which feature cross-needle meter movements that allow simultaneous monitoring of forward power, reflected power, and standing wave ratio. Daiwa also manufactures antenna tuners, coaxial switches, DC power supplies, and antenna rotators for amateur radio installations.
Daiwa equipment has been distributed internationally for decades and remains common in both home and commercial amateur radio stations.
History
Daiwa Industry entered the amateur radio market during the growth of amateur communications in the 1970s. The company established itself as a manufacturer of station accessories and test equipment rather than radio transceivers.
During the following decades, Daiwa expanded its product catalog to include a broad range of station equipment including power meters, antenna tuners, switches, rotators, and power supplies. The company’s products gained popularity due to their durable construction, straightforward operation, and wide availability through amateur radio dealers worldwide.
Today, Daiwa continues to manufacture amateur radio accessories and station equipment for the global amateur radio market.
