The Telstra Smart Modem 4 is a Wi‑Fi 7‑enabled, dual‑band router built for high‑capacity, smart‑home environments. Featuring 5G/4G backup for NBN resilience and EasyMesh compatibility, it delivers seamless, high‑speed connectivity for up to 250 devices. Powered by 2 GB of RAM, the Smart Modem 4 offers faster throughput, enhanced security and broader coverage than the Gen 3 model, making it the ideal hub for modern, connected households.
The Telstra Smart Modem 4 includes built‑in, directional Wi‑Fi antennas that are tuned for optimal coverage inside the home. When the 4G/5G backup link needs a boost, especially in rural or fringe locations, the modem's dual SMA ports allow the connection of external antennas. Our high‑gain panels, directional units or Yagi arrays can be paired with appropriate patch leads to improve the backup signal, while the primary NBN connection remains unchanged.
Any antenna that terminates in a standard SMA connector and supports MIMO operation can be used, including panel, sector and Yagi designs from reputable manufacturers.
Yes, but a dual‑band (3 GHz / 4 GHz) or LTE‑compatible antenna will deliver the best performance across the full range of Telstra’s 4G/5G frequencies.
Use a mobile signal metre app or the modem's signal‑strength readout, point the antenna toward the strongest signal, then lock the orientation once the RSSI stabilizes.
A sturdy mast or wall‑mount bracket is recommended for outdoor panels or Yagi arrays to achieve clear line‑of‑sight to the tower and to avoid obstructions.
No. The external antenna only augments the cellular backup link; the internal Wi‑Fi radios continue to operate independently.
The modem's dual SMA ports are designed for MIMO operation, so each port should receive its own antenna. A splitter is only necessary if you plan to share one antenna between two devices.
Keep the coaxial cable as short as possible, Campad Electronic's antennas and leads use low‑loss cable.
Telstra requires a site assessment for the official 4G Smart Antenna to ensure compatibility and warranty coverage; otherwise, third‑party antennas can be installed without Telstra approval.
The current SMA ports are optimized for 4G LTE frequencies. While some 5G compatible antennas share the same connector, performance may be limited; check the antenna specifications for LTE support.
Log into the modem’s admin portal, navigate to the cellular status page and compare the signal strength (dBm) before and after antenna installation.
Mount the antenna securely, use weather‑proof fittings and avoid placing it near power lines or other sources of RF interference.
Buy at Campad Electronics. Specialised electronics suppliers such as Campad Electronics, as well as major online retailers, list MIMO‑ready antennas that match the modem’s SMA connectors.
