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 broadband omni provides 6 dBi of gain across all carriers — no carrier-specific tuning required.

Why Hills Reliance installers specify D&G

Individually tested

Every antenna is tested on Anritsu Site Master 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. LMR240 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.
