Seaworthy RF
From Vessel to Offshore
D&G Antennas, trading as Xtend Communications, manufactures and distributes RF antennas for vessel telemetry, offshore platform monitoring and coastal IoT infrastructure in Australia. We are a manufacturer and distributor; we do not perform vessel installations. Primary product: DG850MB-CT (698–2700 MHz, 4.5 dBi at 850 MHz and 7.5 dBi at 1.8–2.5 GHz, UV-protected ABS radome, stainless steel bracket, 5 m ALSR195 pre-terminated). High-gain option: DG900MB-HG (7 dBi across 700–1000 MHz) for shore-link uplinks. Custom cable assemblies to any length and connector type. B2B supply from 50 units.

— Applications
Built for Water
Any Environment
Vessel Telemetry
AIS gateway uplinks, engine monitoring, and hull sensor telemetry require antennas that maintain pattern stability across the horizon regardless of vessel motion or heel angle.
Offshore Platform Monitoring
Spray zones and tidal environments are hard on RF hardware. A UV-protected ABS radome on a stainless steel bracket holds up where unprotected plastics and plated steel break down.
Coastal IoT Infrastructure
LoRa and 4G gateway antennas deployed in coastal environments face continuous salt air, UV exposure, and high-humidity conditions. Only marine-grade construction survives long-term.

DG900MB-HG
High-Gain Multiband Omni
Shore-link and gateway uplink. 7 dBi across 700–1000 MHz holds the link budget over water, where surface scatter costs a standard-gain omni its range.
Full Specs & DatasheetUp to 6 GHz
Custom Cable
Custom RF Cable Assembly
Custom-length interconnect runs from antenna to below-deck radio equipment. Any length, N/SMA/TNC/BNC terminations. UV-stable PE jacket.
Full Specs & Datasheet— Aqua Series
Marine-Grade Construction.
No Compromise.
The Aqua Series is built for salt air and exposed deck positions. A UV-protected, high-impact ABS radome and a stainless steel bracket resist the yellowing, cracking and corrosion that shorten the life of unprotected hardware in coastal and offshore deployments.
