RF Without Compromise
Built for Mining
D&G Antennas, trading as Xtend Communications, manufactures and distributes precision 50Ω RF antennas for mining SCADA, plant automation, conveyor monitoring, and vehicle tracking across Australia. We supply RF components only; we do not perform mine site installations. The DG900MB-HG (7 dBi across 700–1000 MHz) handles SCADA loops and PLC/RTU telemetry across large mine sites, and the DGY900-6 Yagi (12 dBi) reaches the tower from fringe sites. High-EMI environments amplify every impedance mismatch — our 50Ω construction eliminates reflected power losses. B2B pricing from 50 units. OEM from 200+ units.

Where We're Deployed
On-Site
SCADA & Automation
Telemetry loops connecting PLCs, RTUs, and SCADA hosts across large mine sites. High-gain antennas overcome losses in long conduit runs between control rooms and field equipment.
Vehicle & Personnel Tracking
Portal ingress/egress systems and open-pit vehicle tracking require directional antennas with focused beamwidth. DGY900 yagis provide precise zone coverage without spillover.
Conveyor Monitoring
Belt slip, misalignment, and blocked chute sensors transmit telemetry via 900 MHz ISM. IP65-rated antennas on steel structures survive vibration and dust ingress that standard parts cannot.
