Key Features & Benefits

• Patented Meander™ PCB Collinear Design — Delivers stable gain and radiation pattern across the full UHF CB band (476–477 MHz). Superior consistency compared to traditional wire wound antennas.

• Q-Fit™ Removable Whip — Tool free removal for low clearance areas, security, or swapping to a shorter whip (e.g., CDQ3000/CDQ34 for city use).
• Heavy Duty Construction — Tapered fibreglass radome, extra heavy stainless steel spring (black chrome options), marine grade fittings. Built to survive corrugations, bull bars, and harsh UV/ weather.
• Ground Plane Independent — Flexible mounting on bull bars, guards, roofs, or mirrors.
• Pre-Tuned, No SWR Adjustment Needed — Full band coverage with VSWR <1.5:1.
• Includes 5m Low-Loss Cable — 9006 cable with FME female + UHF adaptor for easy vehicle routing.

Frequently Asked Questions (FAQ)

Q: Is the RFI CDQ5000 better than GME antennas?

A: RFI often edges out in build quality, pattern stability (thanks to PCB tech), and the removable Q-Fit system. Real-world range tests are very close, but RFI users praise longevity in tough conditions.

Q: Will it fit my vehicle?

A: Yes — standard 16 mm mount suits most bull bars, guards, and brackets. Ground plane independent.

Q: Do I need to tune it?

A: No. Factory pre-tuned for full 80-channel UHF CB band.

Q: How does it compare to 8 dBi antennas?

A: 5 dBi offers better all-round performance (wider beam). 8 dBi (e.g., CDQ8000) is for extreme long distance over flat terrain.

Q: Is it legal in Australia?

A: Fully compliant for UHF CB use (477 MHz).

Q: What’s the warranty?

A: Backed by RFI’s reputation for quality (check retailer for specifics).

Q: Black or white version?

A: Black (CDQ5000-B) for stealth/modern look; white for traditional visibility.
