CradlePoint MINI BLACK LTE/4G/3G 4.5 2/3 — compact cellular modem antenna for mobile broadband

CradlePoint MINI BLACK LTE/4G/3G 4.5 2/3 is a compact cellular modem antenna designed to improve mobile broadband reception for LTE/4G and 3G networks. Intended for use with routers and modems, the antenna offers a small form factor that fits in constrained installations such as vehicles, temporary sites, and remote locations where built-in antenna performance may be limited. The design focuses on compatibility with standard cellular frequency ranges and on providing a practical reception boost for data connections.

Advantages

The compact size allows installation in space-limited environments while maintaining an external antenna gain suitable for improving signal strength and data stability. The antenna is optimized for standard LTE/4G and 3G bands, helping to reduce dropped connections and maintain higher throughput compared with many internal antennas. Its straightforward integration with compatible routers and modems simplifies upgrades to existing mobile broadband setups.

Suitable for

• Vehicle installations where improved cellular signal is required
• Remote or temporary sites with weak indoor reception
• Integration with mobile routers and modems to boost data stability
• Small form-factor deployments where external antennas are preferred

Key specifications

• Supported networks: LTE/4G and 3G cellular bands
• Form factor: compact, low-profile external antenna
• Intended use: mobile broadband signal reception and improvement
• Mounting: suitable for vehicle or small-site external mounting
• Compatibility: designed for integration with compatible routers and modems

How to use

Mount the antenna in a location with the clearest line of sight to the nearest cell tower possible, such as a vehicle roof or an exterior wall. Connect the antenna to the modem or router using the appropriate cable and connector type supported by the host device. After connection, position and, if applicable, adjust the antenna orientation to achieve the best signal strength as indicated by the router or modem diagnostics. Secure all cable runs and ensure connectors are tightened to prevent intermittent loss of contact.

Usage recommendations

For optimal performance, place the antenna where it is least obstructed by metal objects and avoid routing the coaxial cable near sources of electrical interference. If the installation is exposed to weather, use suitable sealing and mounting hardware to protect connections and ensure reliable long-term operation.
