Canarinho American Coil CB Antenna

Steelbras is nationally recognized for excellence in radio communication antennas, and on the citizens band (CB), few products carry as much tradition as the Canarinho line with American Coil.

In this post we present the three models in this family: AP3051, AP3052 and AP3053 — all built with refined engineering, high power handling and outstanding performance at 27 MHz.

The heart of performance: the Steelbras American Coil

(Featured on all three models)

According to the official documentation, the American coil is the key differentiator:

• Handles high, continuous power without excessive heating
• High efficiency with low Joule-effect losses
• Wider bandwidth — ideal for 80-channel CB radios
• Premium construction in chrome-plated brass, UV-protected polymer and painted aluminum

The American coil was designed to deliver maximum power transfer and superior efficiency across the entire CB band.

Solid base and anti-theft system (patented)

The Canarinho family keeps a standard that has become a Steelbras trademark:

• Fully solid internal base
• Prevents poor contact
• Reduces whip sway
• Allows better VSWR tuning
• Unbreakable
• Outer tube locked by crimp points aligned with the inner groove — making the assembly extremely secure and durable

This system ensures greater durability and prevents the antenna from being removed without authorization.
