Overview

Zodiac was a brand used on citizens band (CB) radios during the 1960s and 1970s, primarily associated with equipment manufactured in Japan for export to the United States and other markets.

History

Zodiac CB radios appeared during the period when CB radio demand expanded rapidly in the United States. Like many brands of the era, Zodiac was not a single clearly documented manufacturer but a brand name applied to radios produced by OEM manufacturers.

Most Zodiac radios were:

• Manufactured in Japan
• Imported and distributed by U.S. companies
• Sold through electronics retailers, catalogs, and CB radio dealers

The brand was active during the transition from crystal-controlled radios (mid-to-late 1960s) to fully synthesized 23-channel and later 40-channel units in the 1970s.

Manufacturing Context

Zodiac radios are commonly associated with Japanese OEM production practices, where:

• A single factory produced radios for multiple brands
• Similar or identical chassis appeared under different names
• Model numbers varied by distributor rather than manufacturer

While specific factory attribution is not always documented, Zodiac radios share design characteristics with equipment produced by several known Japanese CB manufacturers of the period.

Technical Context

Zodiac CB radios covered multiple generations of technology:

• Early models used plug-in crystals for channel selection
• Later models provided full 23-channel coverage
• Subsequent units used synthesized (PLL) circuitry for channel selection

These radios typically operated within standard CB specifications for the time, including AM modulation and approximately 4 watts output.

Legacy

Zodiac represents a typical private-label CB radio brand from the peak era of CB popularity. Its products reflect the broader shift of CB radio manufacturing to Japan and the widespread use of OEM production and rebranding in the industry.
