Xtreme Antennas ANT-XA-03
5G Multi-Band Cellular Antenna | 698–4800 MHz | Suits Cel-Fi Roam R41

The ANT-XA-03 from Xtreme Antennas is a heavy-duty, compact solution built to provide reliable mobile coverage in both metro and fringe areas. Engineered with a tuned multi-band PCB-based design, this antenna delivers superior performance across 3G, 4G, and 5G bands, including coverage from 698MHz up to 4800MHz, making it a versatile choice for vehicles operating across Australia’s cellular networks.

Designed for use with Cel-Fi Roam R41, this antenna offers exceptional value and performance for mobile signal boosting applications where space, durability, and signal strength matter.

Key Features:

• Wideband Performance (698–4800MHz): Compatible with all major 3G/4G/5G frequency bands used across Telstra, Optus, and Vodafone networks.

• Optimised for Cel-Fi Roam R41: Direct SMA Male connection and matched impedance make it an ideal external antenna for mobile signal repeaters.

• High Gain Design (3–5dBi): Delivers increased range and stable performance in remote and low-signal areas.

• Compact Medium Duty Spring Base: Built-in spring mount offers flexibility and impact resistance for off-road and mobile use without excessive height.

• LMR195 Low-Loss Coaxial Cable: Includes 4.5 metres of high-quality cable for improved signal transmission and easy installation.

• Ground Independent Design: Performs reliably regardless of vehicle mounting location — ideal for bull bars, mirror brackets, or roof mounts.

Why Choose ANT-XA-03 Over Other Antennas?

• Broader frequency support than most competing antennas (including coverage above 3800 MHz).

• Designed specifically to withstand vibration and environmental exposure typical in 4WD, transport, and caravan setups.

• Compact 680mm profile is shorter than traditional 900mm+ antennas while still offering high gain across bands.
