Hills Reliance XR
External 4G Antenna Kit
The Hills Reliance XR with NXX-4G-WFSIM-AU 4G/WiFi router module uses a standard SMA antenna port. When the module is installed in a shielded location, an external antenna is essential for reliable back-to-base monitoring.

About the Hills Reliance XR 4G Module
The Hills Reliance XR is a leading residential and light commercial alarm panel in Australia. The NXX-4G-WFSIM-AU module adds dual-SIM 4G cellular and WiFi router capability, providing multiple communication paths for back-to-base monitoring.
The 4G module features an SMA Female antenna port for cellular connectivity. In installations where the panel is in a metal enclosure, plant room, or basement, the supplied stub antenna cannot perform adequately — an external replacement is required.

When an external antenna is required
NXX-4G-WFSIM-AU in metal enclosure
The Hills Reliance XR enclosure is metal. The 4G module's antenna inside the enclosure is shielded from signal. An external pigtail and wall-mount omni restores signal — critical for back-to-base communication reliability.
Residential and light commercial basements
Hills Reliance XR is widely used in higher-end residential and light commercial installations. Basement and underground locations require an external antenna routed to ground level or the exterior of the building.
Multi-dwelling unit MDFs
Telecommunications rooms and MDFs in apartment complexes and commercial buildings are typically heavily shielded. External antenna cable routed to the building's external face or plant room roof is the standard solution.
Fringe coverage sites
Semi-rural residential and rural commercial sites with marginal 4G coverage. The multiband omni provides 7 dBi on the 700–1000 MHz low bands — no carrier-specific tuning required.
Recommended D&G Products for Hills Reliance XR
All antennas tested before dispatch. Custom cable assemblies in any length.
DG900MB-HG — High Gain Multiband Omni
External replacement antenna for the NXX-4G-WFSIM-AU module's 4G cellular port. 7.0 dBi at 700–1000 MHz and 3.5 dBi at 1710–2600 MHz — covers the main Australian 4G bands from a single antenna. Wall or pole mount.
XC3800-MIMO — MIMO Omni, Dual Port
For installations where the NXX-4G-WFSIM-AU module supports dual-antenna MIMO configuration. 6 dBi from 1700 to 2700 MHz provides maximum throughput and signal margin. Two separate antenna cables required.
Custom Cable Assembly
Low-loss ALSR195 (lower loss than RG58) or LMR400 for routing external antenna cable from plant room to external mounting location. Custom built to site specification.
Why Hills Reliance installers specify D&G
Tested before dispatch
Every antenna is tested before dispatch. No batch sampling. A failed antenna on a monitoring installation means a compliance failure — we test every unit.
Australian manufacturer
D&G antennas are manufactured at Penrith, NSW. Our components are inside ADT, Johnson Controls, and Wormald monitoring infrastructure across Australia.
Custom cable assemblies
SMA to N connector cables in any length. ALSR195 (lower loss than RG58) or LMR400 low-loss coax for longer conduit runs from plant room to external mounting location.
No minimum order
One antenna for a problem site, or bulk supply for a portfolio of Hills Reliance XR installations. Dealer pricing available for ongoing volume.
