Externá okenná anténa HUAWEI A77 pre príjem LTE/4G, magnetický držiak, s káblom

The HUAWEI A77 external window antenna is designed to improve LTE/4G mobile broadband reception for indoor routers, modems and gateways. The unit is intended to be mounted on or near a window and delivers a fixed cable and connector for direct connection to compatible cellular devices. By relocating the antenna element to a position with better line-of-sight to cell towers, the antenna helps stabilize signal strength and reduce fluctuations in areas with weak indoor coverage.

Advantages

The antenna uses a magnetic mount for quick and secure placement on metal surfaces near windows and a factory-fitted cable for straightforward connection without additional adapters. Its design focuses on passive signal reception to enhance LTE/4G performance of connected equipment, improving download and upload stability while maintaining compatibility with a range of consumer cellular gateways and routers. The compact form factor and cable-ready connector minimize installation time and visual impact.

Suitable for

• Improving 4G/LTE reception for home or small office routers and modems
• Locations with weak indoor cellular coverage where window placement can provide better signal
• Temporary setups or fixed installations requiring a simple magnetic mounting solution

Key specifications

• Frequency coverage: LTE/4G bands (designed for cellular mobile broadband)
• Mounting type: magnetic mount suitable for window-adjacent metal surfaces
• Cable: fixed cable with ready-made connector for direct device connection
• Intended use: external window placement for indoor signal improvement
• Compatibility: designed for use with routers, modems and gateways that accept external cellular antennas

How to use

Place the antenna on a window frame or nearby metal surface where it has the clearest possible view toward the cell tower direction. Run the fixed cable to the router or modem and connect the antenna connector to the device’s external antenna port. If the device has more than one antenna input, follow the device manufacturer’s guidance for antenna placement and port assignment. Test signal strength and, if needed, try alternative positions along the window to find the location that provides the best reception.

Recommendations

For best results, position the antenna on the side of the window facing the nearest cell tower and avoid placing it behind thick metalized glass or obstructive building materials. Secure cable routing to prevent strain on the connector and periodically check connections to ensure continued performance.
