Aerpro CBA230 2.0-3.0dBi On-Glass UHF CB Antenna 477MHz

Aerpro CBA230 2.0 to 3.0dBi On-Glass Self-Adhesive UHF CB Antenna 477MHz Ground Independent with 3 Metre RG58 FME Cable and PL259 Adaptor

The Aerpro CBA230 is a 477MHz on-glass UHF CB antenna with 2.0 to 3.0dBi gain, designed for vehicles where an external antenna mount is not possible or desirable. A clear self-adhesive mount attaches directly to the inside of a windscreen or rear window with no drilling, no roof holes, and no permanent modifications. Supplied with a 3-metre RG58 coaxial cable terminated with a female FME connector and an FME to PL259 adaptor for a complete ready-to-install solution.

Product overview

The CBA230 suits vehicles where a traditional rooftop or bull bar antenna mount is not practical, including glass-roofed SUVs, work vehicles where roof penetration is not permitted, and users who want a clean, unobtrusive installation without permanent modification. The white and clear antenna element sits discreetly against the glass surface.

The 2.0 to 3.0dBi gain and broad radiation pattern suit urban, suburban, and built-up environments where communication range is typically shorter and signals need to work in multiple directions rather than concentrating gain along a single axis. The ground-independent design maintains a consistent radiation pattern regardless of the vehicle body around it, unlike magnetic mount or rooftop-mount antennas that rely on a ground plane for correct operation. The 50 Ohm impedance and linear polarisation ensure compatibility with standard Australian 477MHz UHF CB radio installations.

Features and benefits

On-glass self-adhesive mount no drilling or permanent modification: Attaches directly to the inside of a windscreen or rear window using a clear adhesive mount. No roof holes, no external hardware, no permanent modification to the vehicle.

Ground independent design: Maintains a consistent radiation pattern regardless of mounting position on the vehicle, unlike antennas that require a metal ground plane for correct operation.

2.0 to 3.0dBi gain with broad radiation pattern: Well matched to urban, suburban, and built-up environments where signals need to work across multiple directions.

477MHz frequency - suits all Australian UHF CB radios: Compatible with all major brands of 477MHz UHF CB radios used in Australia and New Zealand.

50 Ohm impedance and linear polarisation: Consistent with standard UHF CB radio installation requirements.

3-metre RG58 FME cable included: Dedicated coaxial cable terminated with a female FME connector provides cable length for routing from the antenna to the radio.

FME to PL259 adaptor included: Allows direct connection to UHF radios using the standard PL259 antenna socket without additional adaptors.

Low-profile white and clear appearance: Blends neatly against glass for an unobtrusive, clean look in the vehicle cabin.

Frequently asked questions

What vehicles is the CBA230 suited to? The CBA230 suits any vehicle where a traditional rooftop or external antenna mount is not practical or permitted. Common applications include glass-roofed SUVs, work vehicles where roof penetration is not permitted, and installations where a clean, non-permanent solution is preferred. The adhesive mount attaches to the inside of a windscreen or rear window.

What does ground independent mean for this antenna? Most traditional antennas require a metal ground plane beneath the antenna base to operate correctly, which is why rooftop and magnetic mount antennas rely on the vehicle body. A ground-independent antenna does not need a ground plane and maintains consistent performance regardless of where it is mounted on the vehicle.

Will the 2.0 to 3.0dBi gain be sufficient for my needs? The 2.0 to 3.0dBi gain and broad radiation pattern are well suited to urban, suburban, and built-up environments where communication distances are typically shorter and signals need to work across multiple directions. For remote outback use where maximum range is the priority, a higher-gain external rooftop antenna may be more appropriate.

What connector does the cable use and what is the FME to PL259 adaptor for? The 3-metre RG58 cable is terminated with a female FME connector. The included FME to PL259 adaptor allows connection to UHF CB radios fitted with the standard PL259 (SO-239) antenna socket, which covers the majority of fixed mount UHF CB radios.

Can the CBA230 be mounted on the rear window instead of the windscreen? Yes. The self-adhesive mount attaches to the inside of any suitable glass surface including the rear window. Rear window mounting may suit some vehicle layouts better than windscreen mounting depending on cable routing and radio location.
