Antenna DELOCK 10040 5G LTE SMA connector 3 dBi omnidirectional

DELOCK 10040 is a 5G LTE omnidirectional antenna with an SMA connector and 3 dBi gain, designed to improve cellular signal reception for routers, modems and gateways. The antenna provides uniform coverage in all directions, making it suitable for use in indoor or sheltered outdoor locations where consistent reception across a room or small area is required. The included RG-174 cable and SMA plug allow straightforward connection to devices with an external antenna port.

Advantages

The antenna offers a compact and unobtrusive form factor with omnidirectional coverage and a modest 3 dBi gain that can stabilise connections and increase effective range for connected 5G LTE equipment. Its SMA connector and 3 m RG-174 cable provide easy installation and flexible placement options without requiring specialised tools. The design targets improved reception for common cellular network tasks while remaining compatible with many routers and LTE modems that use SMA external antenna ports.

Suitable for

• Improving indoor cellular signal for 5G LTE routers and modems
• Small office or home installations where uniform coverage is needed
• Devices with an external SMA antenna port supporting 5G LTE
• Temporary or semi-permanent setups using the included RG-174 cable

When it may not be suitable

This antenna has a moderate 3 dBi gain and omnidirectional pattern; it is not intended for long-distance, point-to-point links or scenarios that require high directional gain. It may not provide significant improvement in locations with very weak network coverage or where outdoor roof-top mounting and professional-grade weatherproofing are needed.

Key specifications

• Frequency band: 5G LTE compatible ranges
• Radiation pattern: omnidirectional
• Gain: 3 dBi
• Connector: SMA plug
• Cable type and length: RG-174, 3 m
• Usage environment: indoor or sheltered outdoor

How to use

Connect the SMA plug to the external antenna port of your router, modem or gateway. Place the antenna in a location with the best possible cellular reception, preferably elevated and clear of large metal objects or dense building materials. Route the RG-174 cable to the device, avoiding sharp bends or kinks. After connection, verify signal strength on the device and adjust the antenna position to achieve the most stable reception.

What to consider before purchase

• Confirm your device has an SMA external antenna port compatible with a male SMA plug.
• Assess whether a 3 dBi omnidirectional antenna is sufficient for your coverage needs versus a higher-gain or directional antenna.
• Verify intended installation location is suitable for an indoor or sheltered outdoor antenna and that cable length meets placement requirements.

Usage recommendations

For best results, mount the antenna as high as practical indoors and away from metal enclosures. If signal improvement is limited, consider testing different positions near windows or comparing with a higher-gain or directional antenna suited to your specific coverage challenges.
