About the Ness D8X / D16X 4G Dialler
The Ness D8X and D16X are widely used residential and light commercial alarm panels. The 4G dialler module (model 106-096) adds 4G cellular alarm reporting capability, providing back-to-base communication via IP or SMS path.
The 4G dialler ships with a 3 dBi magnetic base antenna on a 2.9 m cable. This is adequate for unshielded installations with reasonable 4G coverage. Where the antenna is inside a metal panel box, or where coverage is marginal, an external higher-gain antenna is required.

When an external antenna is required
Replacing the supplied 3 dBi magnetic whip
The Ness 4G dialler ships with a 3 dBi magnetic base whip on a 2.9 m cable. Where the cable is coiled inside the panel or the whip is positioned inside a metal enclosure, signal is heavily attenuated. External wall-mount omni eliminates this problem.
Residential in metal comms enclosure
Ness D8X and D16X are common in residential and light commercial installations where the panel is in a metal box. The metal enclosure completely blocks the magnetic base whip. An external cable and wall-mount antenna restores reliable 4G.
Rural and fringe-coverage residential
Rural residential properties and hobby farms at the edge of 4G coverage. The Yagi upgrade provides 11 dBi directional gain toward the nearest tower — often the difference between failed and reliable alarm signalling.
Light commercial — shops and offices
Small commercial premises with Ness D8X panels in plant rooms, store rooms, or roof spaces. External omni mounted at the external face of the building provides consistent signal regardless of internal building structure.

Why Ness installers specify D&G
Tested before dispatch
Every antenna is tested on Anritsu Site Master before it leaves our facility. A failed antenna on a residential alarm site means a callback — we eliminate that before the product ships.
Australian stock, no wait
Antennas in stock at Penrith. No import lead time. For residential and light commercial installers running multiple jobs, consistent product availability is essential.
Any cable length, any run
The Ness 4G dialler's supplied 2.9 m cable is replaced with a custom low-loss assembly matched to the cable run from panel to external antenna mount. SMA Male and N connector options.
No minimum order
One antenna for a problem site, or a box of 20 for a new development. Same test standard, same quality, no minimum.
