Oricom ANU236 6.5dBi Ground-Independent UHF CB Antenna

High-gain ground-independent antenna with elevated feed for versatile bull bar mounting

The Oricom ANU236 6.5dBi UHF CB Antenna delivers extended communication range through ground-independent design with elevated feed technology. This 960mm antenna system eliminates the need for vehicle ground plane dependency, providing consistent performance across various mounting positions and vehicle types. The 6.5dBi gain specification focuses signal energy horizontally for increased distance on flat terrain including deserts, plains, salt lakes, and coastal areas.

The elevated feed design optimizes antenna performance regardless of mounting surface conductivity, making this antenna suitable for bull bar installations on steel, aluminium, or composite materials. The heavy-duty barrel spring base absorbs offroad impacts while the black powder-coated finish protects against corrosion in Australian conditions. The antenna features a 5/16 UNC threaded whip (not the spring base) for secure attachment and potential replacement options. Complete with 4.5-metre low-loss coaxial cable, pre-terminated FME connector, and PL259 adaptor, the ANU236 provides everything needed except the vehicle-specific mounting bracket.

Whether touring open country, coordinating convoys across long distances, or maintaining communications in remote areas, this ground-independent design delivers consistent high-gain performance across diverse vehicle platforms.

Features & Benefits

Ground-Independent Design — Elevated feed eliminates dependency on vehicle ground plane, providing consistent performance across steel, aluminium, or composite bull bars without tuning or performance variations.

6.5dBi High Gain — Extended range performance on flat terrain significantly increases communication distances compared to 3dBi antennas, critical for desert crossings, plains touring, and convoy coordination.

Elevated Feed Technology — Optimized feed point positioning ensures proper antenna operation regardless of mounting surface material or conductivity, simplifying installation across diverse vehicle platforms.

960mm Length — Mid-length high-gain design balances extended range capability with practical clearance considerations, shorter than 1140mm alternatives while maintaining 6.5dBi performance.

Heavy-Duty Barrel Spring Base — Absorbs impacts from obstacles and offroad terrain, protecting the antenna system under demanding conditions while maintaining flexibility for branch strikes.

5/16 UNC Threaded Whip — Standard thread specification enables secure attachment and facilitates potential whip replacement options using compatible aftermarket or replacement components.

Bull Bar Mounting Versatility — Ground-independent design suits various bull bar configurations and materials, with multiple mounting options available through appropriate brackets.

Complete Installation Kit — Includes 4.5-metre low-loss coaxial cable, pre-terminated FME connector, and PL259 adaptor for immediate installation once mounting bracket is sourced.

Black Powder Coat Finish — Durable coating protects against UV degradation, salt corrosion, and chemical exposure while matching modern vehicle aesthetics.

Three-Year Warranty — Extended warranty coverage reflects manufacturer confidence in ground-independent antenna durability for demanding Australian touring applications.

Frequently Asked Questions

What does "ground-independent" mean?

Ground-independent antennas don't rely on the vehicle body as part of the antenna system. The elevated feed design ensures consistent performance regardless of mounting surface material (steel, aluminium, composite) or electrical conductivity.

What mounting bracket do I need?

The ANU236 requires a vehicle-specific bull bar mounting bracket (sold separately). Bracket selection depends on your bull bar type, diameter, and preferred mounting position. Consult mounting bracket specifications for compatibility.

Can I use this antenna on a roof rack instead of bull bar?

The antenna is designed and optimized for bull bar mounting. While ground-independent design provides flexibility, verify clearance and mounting bracket availability before considering alternative mounting positions.

Why is this antenna shorter than the ANU806PNK but still 6.5dBi?

The elevated feed design achieves 6.5dBi gain in a more compact 960mm length compared to conventional 1140mm designs, providing extended range with reduced clearance requirements.

What's the thread size for the spring base?

The 5/16 UNC thread specification applies to the whip only, not the spring base. The spring base has a separate thread specification for mounting bracket attachment. Verify bracket compatibility before purchase.
