Antenna DELOCK 10037 5G LTE SMA connector omnidirectional gain 3–5 dBi

DELOCK 10037 is a compact 5G LTE omnidirectional antenna with an SMA connector and a specified gain range of 3–5 dBi. It is designed to connect to mobile routers, modems and other network devices that provide an external antenna port. The antenna supports cellular frequency bands used for LTE and 5G applications and aims to improve reception and transmission in environments where internal antennas are insufficient. Its discreet form factor and standard SMA interface make it compatible with a wide range of consumer and small business networking equipment.

Advantages

The omnidirectional radiation pattern provides uniform coverage around the antenna, reducing the need for precise alignment. A gain of 3–5 dBi offers a balance between broader coverage and focused signal improvement, suitable for typical indoor and near-outdoor installations. The SMA connector ensures easy and tool-free attachment to devices with an SMA female socket. The antenna’s compact size and straightforward mounting options allow installation on walls, windowsills or desktop positions without major modifications.

Suitable for

• Home and apartment LTE/5G signal enhancement
• Small office and retail environments needing improved cellular connectivity
• Mobile routers and modems with external SMA antenna ports
• Temporary setups and field testing where quick antenna changes are required

Key specifications

• Type: Omnidirectional external antenna
• Connector: SMA male
• Gain: 3–5 dBi (frequency-dependent)
• Frequency coverage: cellular LTE and 5G bands (multiband support)
• Form factor: compact, cylindrical/rod-style antenna
• Installation: desktop, wall or window mounting options

How to use

Attach the antenna to the SMA female connector on your router, modem or compatible network device by hand-tightening the SMA connector until secure. Position the antenna vertically for omnidirectional coverage and place it in an elevated location near a window or away from large metallic obstructions to maximise signal reception. After installation, check your device’s signal strength indicators or carrier tools and, if possible, test a few positions to find the location with the best performance. For devices with multiple antenna ports, follow the device manufacturer’s guidance on antenna port assignment and diversity configuration.

Recommendations

Use the antenna in a dry environment and avoid exposing connectors to prolonged moisture. If external mounting outdoors is required, use additional weatherproofing accessories at the connector interface and follow local installation best practices. For optimal performance, pair the antenna with compatible devices that allow external antenna connections and verify supported frequency bands to ensure coverage of your carrier’s LTE/5G channels.
