Digi International 76000960 Indoor LTE/4G/3G Antenna
Overview
The Digi International 76000960 is a compact indoor antenna engineered for LTE, 4G, and 3G deployments operating in the 410/450 MHz frequency bands. At 109 x 10 mm, it mounts directly via an SMA male connector — no pigtail adapters, no additional mounting hardware for most router and gateway enclosures. If you are deploying Digi cellular routers or gateways in control rooms, server closets, or equipment cabinets where the device lives indoors, this antenna is the straightforward path to a clean, permanent installation without routing coax to an exterior wall.

Key Features
- 410/450 MHz LTE/4G/3G Coverage: Tuned for the 410 and 450 MHz bands used by private LTE networks, SCADA carriers, and utility-grade cellular infrastructure — not a generic broadband antenna repurposed for these frequencies. If your deployment relies on FirstNet, a private LTE grid, or a 450 MHz carrier, the frequency match matters more than antenna gain numbers.
- Direct SMA Male Connector: Threads directly into SMA female ports on compatible Digi gateways and routers — no adapter, no coax run, no insertion loss from an intermediate connector. Cleaner RF path, one fewer failure point.
- 109 x 10 mm Form Factor: The pencil-thin 10 mm diameter means it fits inside most equipment enclosures without clearance issues. At just over 4 inches long, it sits flush enough that cabinet doors and rack panels close normally — a practical consideration in dense equipment rooms.
- ABS Construction: The ABS plastic housing is lightweight and RF-transparent, so the housing itself does not attenuate the signal. It also handles accidental contact better than exposed whip antennas in high-traffic equipment areas.
- -40 to 85°C Operating Range: Most indoor environments will never challenge this range, but it matters in industrial control panels, outdoor-rated enclosures used indoors, or unheated equipment rooms in cold climates. The 85°C upper limit also keeps the antenna operational near heat-generating equipment without performance degradation.
- Indoor Environment Rating: Rated and designed for indoor use — appropriate for equipment rooms, server closets, retail back-of-house, and similar controlled environments. Not intended for direct outdoor exposure or wash-down environments.
- 5-Year Manufacturer Warranty: A five-year coverage period on a passive antenna component is meaningful — antennas in fixed installations are often forgotten until they fail. This warranty horizon matches typical infrastructure refresh cycles.
Integration and Compatibility
The 76000960 is designed for use with Digi International cellular routers and gateways that feature SMA female antenna ports, particularly devices operating on 410/450 MHz LTE or legacy 3G/4G networks. Verify your gateway's supported frequency bands before ordering — this antenna is optimized for 410/450 MHz and will underperform on higher-frequency bands such as 700 MHz or 1900 MHz. For applications requiring outdoor antenna placement, consider an external antenna with appropriate weatherproofing and a coax run back to the gateway. Pair this antenna with compatible cellular routers and IoT gateways for a complete indoor deployment.
Frequently Asked Questions
Q: What frequency bands does the 76000960 support?
A: The 76000960 is tuned for LTE/4G/3G operation in the 410 and 450 MHz frequency bands. It is not a wideband antenna and is not optimized for higher cellular frequency bands.
Q: What connector type does the 76000960 use?
A: It uses a direct SMA male connector, which threads into SMA female ports on compatible Digi International gateways and routers without requiring an adapter cable.
Q: Can the 76000960 be used outdoors?
A: No. The 76000960 is rated for indoor environments only. For outdoor deployments, a weatherproofed external antenna with a coax feed is required.
Q: What is the operating temperature range of the 76000960?
A: The antenna is rated from -40°C to 85°C, covering virtually all indoor industrial environments including unheated equipment rooms and control panels near heat-generating equipment.
Q: What is the warranty on the 76000960?
A: The 76000960 carries a 5-year manufacturer warranty.
Q: What are the physical dimensions of the 76000960?
A: The antenna measures 109 x 10 mm (approximately 4.3 inches long, 0.4 inches in diameter), making it compact enough for use inside most equipment enclosures without clearance concerns.
The detail that stands out to me on the 76000960 is the 410/450 MHz frequency tuning. Most integrators default to sourcing generic LTE antennas rated across wide frequency ranges, but wide-band antennas often sacrifice gain at specific frequencies. If your deployment is on a private LTE network or a utility-grade carrier operating at 410 or 450 MHz, the 76000960 is purpose-tuned for that range — and that specificity matters when you are trying to maintain a reliable link inside a metal equipment enclosure.
Technical Highlights:
- 410/450 MHz Tuning: Matched to private LTE and utility carrier bands — not a repurposed wideband antenna. Expect better in-band performance than a generic multiband whip in this frequency range.
- Direct SMA Male Mount: Eliminates the coax pigtail common on external antennas, removing one connector joint and the insertion loss and mechanical failure risk that comes with it.
- -40 to 85°C Range: The 85°C upper limit is the spec worth noting — it keeps this antenna viable in control panel interiors where ambient temps near heat-generating equipment can push well above typical room temperature.
Deployment Considerations:
- Confirm your Digi gateway's antenna port frequency band before ordering. The 76000960 is optimized for 410/450 MHz — pairing it with a device operating primarily on 700 MHz or higher bands will leave performance on the table.
- This is an indoor-only component. If your enclosure has any exterior exposure or is subject to condensation, moisture ingress, or wash-down, this antenna is not the correct choice — you will need an IP-rated external antenna with a coax run.
The 76000960 is the right fit for private LTE SCADA deployments, utility telemetry cabinets, and industrial IoT gateway installations where the cellular device lives fully indoors and the carrier operates in the 410/450 MHz band.
