— Industry Solutions
Apex Series · High-Gain · Long-Range
Mining
High-gain antennas amplify industrial noise. We manufacture components precision-tuned for resonance, ensuring telemetry survives high-EMI and high-vibration zones where standard parts fail.
Aqua Series · Vessel · Offshore Grade
Marine
Gain is useless if the radiation pattern breaks in a swell. Our marine assets prioritize impedance matching and pattern consistency to keep your link budget intact across the horizon.
Apex Series · ADT · Johnson Controls · Wormald
Fire & Security
Preferred RF component supplier to ADT, Johnson Controls, and Wormald for Centaur and Centair 2 monitoring modules deployed across AU & NZ. Built for uplinks that cannot fail.
Aura Series · Telemetry · LoRaWAN
Industrial IoT
In LoRaWAN and MIOTY deployments, efficiency is the only metric that matters. Our antennas are tuned to minimize packet loss and maximize battery longevity across high-density node networks.

— Why Xtend
Trusted by ADT, Johnson Controls, Cardtronics, and the teams inside Australia's critical infrastructure. Now direct to your project.
D&G Antennas — the engineering team behind Xtend — has been manufacturing and supplying mission-critical RF components across Australia and New Zealand for some of the country's most demanding applications.
D&G RF components are the product inside every Elsema and MultiComm unit sold in Australia. When a brand trusts you to build the thing inside their thing, that's the highest form of specification.
Every product maintains professional 50 Ohm impedance. No 75 Ohm crossover. No domestic product dilution. If it's in our catalog, it's specified for industrial and commercial environments.
200–500 unit orders are our normal. Strategic pricing at 50+ units. Account management for EPC contractors, integrators, and wholesale distributors who need a supplier that won't blink.
Made-to-specification RF cable assemblies for every band up to 6 GHz, on ALSR195 low-loss cable (lower loss than RG58) as standard. Any connector. Any length. Quoted against your system drawings — not a catalogue SKU.
Every product ships with engineering documentation. Full specifications, radiation patterns, and S-parameter data available on request. Your RF Engineer gets what they need to defend the spec.
