AXIS CR814 - AM/FM Antenna Extension 4M

AXIS CR814 - AM/FM Antenna Extension 4M

4-metre Harada-compatible AM/FM antenna extension cable designed for extending factory car radio antenna connections where additional cable length is required between antenna and head unit, compatible with Harada antenna systems commonly fitted to Japanese and Australian-delivered vehicles, enables antenna relocation during dashboard modifications or aftermarket head unit installations requiring extended cable reach, suitable for vehicles with factory antenna mounting relocated during bull bar installation, roof rack additions, or body panel replacements, ideal for custom car audio installations, vehicle modifications requiring antenna repositioning, and any application where standard factory antenna cable length is insufficient to reach relocated head units or modified mounting positions.

Product Overview

The AXIS CR814 is a 4-metre antenna extension cable engineered for Harada antenna systems, the predominant factory antenna brand fitted to many Japanese-manufactured vehicles sold in Australia including Toyota, Nissan, Mazda, Honda, Subaru, and Mitsubishi models. When installing aftermarket head units, relocating dashboards, or modifying vehicle bodywork, the factory antenna cable often becomes too short to reach the new head unit location. This extension cable provides the additional four metres of length needed to bridge the gap between antenna base and relocated head unit without requiring complete antenna replacement. The Harada-compatible connectors ensure proper fitment with factory antenna systems maintaining signal quality for AM and FM radio reception. Common scenarios requiring extension cables include: installing double-DIN head units in vehicles originally fitted with single-DIN units requiring dashboard relocation, mounting head units in custom console locations, relocating antennas during bull bar installation where original fender mounting is obstructed, or routing antenna cables around newly installed equipment like UHF radios or amplifiers occupying original cable routing space.

Important Notes:

Harada System Specific: This extension is designed for Harada antenna systems. Verify your vehicle uses Harada antennas before purchasing.

4 Metre Length: Provides 4m additional reach. Longer extensions introduce more signal loss than shorter alternatives.

Signal Quality: Each extension introduces slight signal loss. Minimize extensions where possible for optimal AM/FM reception.

Connector Compatibility: Ensure connectors match your specific Harada antenna configuration. Some models have different connector types.

Not Universal: This is NOT a universal antenna extension. It's specifically for Harada systems common in Japanese vehicles.

Frequently Asked Questions

Q: How do I know if my vehicle has a Harada antenna system?

A: Check your vehicle's antenna base or consult your vehicle manual. Harada is common on Japanese-manufactured vehicles including many Toyota, Nissan, Mazda, Honda, Subaru, and Mitsubishi models. If your antenna is factory-fitted and you drive a Japanese vehicle, there's good probability it's Harada. Alternatively, check the connector at the back of your head unit - compare with product images or bring photos to us for verification.

Q: Will this 4-metre extension reduce my radio reception quality?

A: Yes, longer extensions introduce more signal loss than shorter ones. A 4m extension typically causes 4-8dB signal loss depending on cable quality and frequency. In strong signal areas (metropolitan locations, near transmission towers), this loss may be acceptable. In marginal reception areas (rural locations, valleys, underground car parks), you will likely experience noticeably reduced reception quality, particularly for weaker AM stations. Consider shorter extensions or antenna/head unit relocation if reception becomes unsatisfactory.

Q: Can I connect multiple extensions together for even longer reach?

A: Not recommended. Connecting multiple extensions compounds signal loss significantly. A 4m extension already introduces considerable signal degradation - adding another extension would likely result in poor or unusable reception, especially for AM radio. If 4m is insufficient, strongly consider: (1) relocating your head unit closer to the antenna, (2) relocating your antenna closer to the head unit, or (3) installing a new antenna with longer factory cable.

Q: Will this work with my aftermarket head unit?

A: Yes, if your vehicle originally had a Harada antenna system. The extension goes between factory Harada antenna and any head unit (factory or aftermarket). The extension doesn't care about head unit brand - it simply extends the antenna cable. Ensure your aftermarket head unit has appropriate antenna input connector matching your vehicle's factory setup.

Q: Can I use this for amplified or powered antennas?

A: If your Harada antenna is powered (receives 12V from head unit for amplification), this extension should maintain power transmission. However, voltage drop over 4m extension may significantly affect amplifier performance. Test before permanent installation to ensure powered antenna operates correctly. Most factory Harada antennas are passive and don't require power.
