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.
