Car Radio Antenna Automatic Power Booster Kit with 990mm Stainless Steel Mast for 12V Vehicles

This automatic car antenna kit is designed to improve AM/FM radio reception by boosting the signal through a powered extendable mast. It eliminates the need for manual adjustment, raising and lowering the antenna automatically with your vehicle's ignition. The stainless steel five-section mast extends to 990mm for effective reception, and the waterproof construction ensures reliable operation in all weather conditions. Suitable for most 12V DC vehicles, this kit includes a 3C-2V coaxial cable and simple three-wire wiring for easy installation.

Features and Construction

Built from durable materials with a focus on signal performance and long-term reliability, this antenna kit offers a practical upgrade for any car radio system. Its design includes proven components such as an imported micro-relay and low-noise circuitry.

Material and Build

The antenna mast is made of five sections of high-grade stainless steel, providing strength and resistance to rust and corrosion. The mast is 990mm long when extended and retracts fully when power is off. The system includes a protective bottom plate measuring 305mm for added stability. A waterproof seal protects the internal electronics from moisture.

Size and Practical Fit

The mast length of 990mm (39 inches) is ideal for good FM reception while remaining compact when retracted. The cable length of 1400mm gives you flexibility in routing the signal cable to your radio. The installation angle can be adjusted from 0 to 30 degrees to suit different vehicle body shapes.

Uses and Placement

This automatic antenna is designed for use in cars, trucks, and vans that operate on a 12V DC electrical system. It is suitable for both daily driving and professional fleet vehicles where reliable radio reception is important.

Event or Professional Use

For fleet vehicles or sales cars, this antenna ensures that drivers always have clear radio reception without needing to manually extend or retract the antenna. The automatic function reduces the risk of damage when entering garages or car washes.

Everyday Home Use

For personal vehicles, this kit eliminates the need to remember to lower the antenna before parking. It provides consistent signal quality for listening to news, music, or traffic updates during the daily commute.

Benefits and Buying Value

This antenna kit offers practical advantages through its automatic operation and durable construction. The stainless steel mast and waterproof design contribute to a long service life with minimal maintenance.

Reuse and Low Maintenance

The stainless steel mast is designed for over 50,000 extend/retract cycles, ensuring years of reliable operation. The low-noise (below 50dB) electronics require no regular maintenance beyond occasional cleaning of the mast.

Why Choose This Product

With its three-wire wiring system, this antenna can be configured to match either an always-on power source or a switched circuit, giving you control over its behaviour. The 3C-2V coaxial cable with 75 ohm impedance is standard for car radio installations, ensuring easy connection to most aftermarket or factory radios.
