Pixel EM-4GE
External 4G Antenna
The Pixel EM-4GE series — EM-4GE1/1L, EM-4GE2/1L, and EM-4GE2/4L — are Australian-made 4G lift emergency phone gateways with a standard SMA Female, 50Ω external antenna port. This guide covers the correct D&G antenna and cable for every machine room scenario.

About the Pixel EM-4GE Series
Pixel Technologies (Sydney) manufactures the EM-4GE series specifically for the Australian vertical transport market. All models are AS1735.19 and EN81-28 certified, RCM approved, and distributed in New Zealand by Cirrus International (Christchurch).
The FXS interface provides a 48V DC loop current and 90V AC ring voltage — a direct PSTN replacement for existing lift car phone wiring. Automated 3-day test calls to the monitoring centre are mandated under AS1735.19 and are built into the gateway firmware. SMS alerts for battery-low, mains-loss, and battery-fail are configurable to up to 3 nominated contacts.

Common installation scenarios
EM-4GE1/1L in roof plant room
Single-lift installations typically use the EM-4GE1/1L in a roof-level machine room. A DG900MB-HG omni mounted on the plant room wall or rooftop parapet connects directly to the gateway on its own SMA Male lead.
EM-4GE2/4L serving a 4-lift bank
The EM-4GE2/4L aggregates up to 4 lift emergency phones onto a single gateway and a single antenna. One DG900MB-HG serves the entire bank — there is no requirement for one antenna per lift car.
Basement machine room — long cable run
Machine rooms below ground level require an LMR400 cable run of 10–15 m from the EM-4GE gateway up to an external antenna at street level or on the building exterior. D&G builds these assemblies to exact site length.
Low-signal site — Yagi for link margin
On fringe-coverage sites, the DGY900-6 Yagi provides 12 dBi of directional gain pointed at the nearest Telstra or Optus tower. Particularly effective for rural or semi-rural lift installations where omni gain is insufficient.
Recommended D&G Products for Pixel EM-4GE
All antennas and cable assemblies tested before dispatch. Custom cable assemblies quoted to site drawings.
DG900MB-HG — High Gain Multiband Omni
Primary external antenna for all EM-4GE models. Outdoor wall or mast mount. Covers all Telstra and Optus 4G bands. For the EM-4GE2/4L, a single DG900MB-HG provides coverage for the entire 4-lift bank — the gateway aggregates all emergency calls onto one antenna port.
DGY900-6 — Yagi Directional Antenna
For low-signal machine rooms and basement installations. Point toward the nearest Telstra or Optus tower to recover maximum link margin. Recommended where the stub antenna or omni delivers marginal RSSI on site survey.
Custom Cable Assembly
ALSR195 (lower loss than RG58) for runs up to 10 m. LMR400 for runs of 10–15 m from machine room to rooftop antenna mount. Built to your site drawing — SMA or N connector at each end.
Why lift companies specify D&G
Active vertical transport supplier
D&G is an active supplier to the Australian vertical transport industry including Hamilton Elevators NSW. We understand machine room constraints, cable routing requirements, and AS1735.19 compliance needs.
100% tested before dispatch
Every antenna and cable assembly is tested before it leaves our Penrith warehouse. A failed antenna in a lift machine room is a compliance breach — we eliminate that risk at source.
Custom cable lengths, any run
Machine room layouts vary. We build ALSR195 (lower loss than RG58) and LMR400 cable assemblies from 1 m to 20 m with SMA Male and N Male terminations to match the EM-4GE port and D&G antenna exactly.
Stocked in Penrith
No import lead times. Standard items available for same-day collection from Penrith. Custom cable assemblies on a 2-week build lead time.
