Your Stable 4G Signal, No Matter Where You Go
Whether on the open sea, a remote campsite, or simply at home in a region with poor mobile Network coverage – a reliable internet connection is essential. The ALFA AOA-M4G was developed precisely for these scenarios. As a true omnidirectional Antenna, it captures 4G signals from a 360° radius. The crucial advantage: You never have to align it with a cell tower. This makes it the perfect 4G omnidirectional antenna for motorhomes, boats, or any location where your position changes or multiple cell towers are in different directions.
Built for the Elements: Absolutely Seawater-Resistant
The term 'Marine Grade' is not an empty marketing promise here. The AOA-M4G is encased in an extremely durable fiberglass housing. This material is not only resistant to UV radiation and extreme temperatures but also absolutely resistant to the corrosive effects of saltwater. This makes it the ideal seawater-resistant Marine 4G Antenna for use on yachts and boats. A maximum wind load of up to 60 m/s underlines the robust construction and ensures trouble-free operation even in strong storms.
Flexible and Compatible: Easy Integration
The Antenna features a professional N-Female connector (N-socket) on the underside. This standard allows for the connection of high-quality and low-loss coaxial cables to maximize signal quality on the way to the end device. You can connect the AOA-M4G to a variety of devices, from specialized outdoor modems to common home routers. For connection to many popular 4G / 5G Routers like a Fritz!Box or Teltonika models, you only need a suitable Antenna Cable (e.g., N-male to SMA-male connector) to establish a perfect connection.
Maximum Performance for 2G, 3G, and 4G
The AOA-M4G is a passive weatherproof 4G 4G Outdoor Antenna that significantly improves the reception of your existing router or modem. It covers all important European frequency bands from 698 MHz to 2700 MHz, making it suitable for all 2G, 3G, and 4G networks. In the long-range bands below 1 GHz, it offers a solid gain of 4 dBi, while in the higher frequency bands for higher speeds, it even achieves a gain of 6 dBi. This ensures that your router always receives the best possible signal.
Strengths & Notes at a Glance

Frequently Asked Questions (FAQ)
Is the ALFA AOA-M4G a 5G Antenna?
No, the AOA-M4G is primarily designed for 4G/LTE, 3G, and GSM and covers frequencies up to 2700 MHz. For 5G, higher frequency bands are often used, for which ALFA offers the successor model AOA-M5G.
Can I connect this antenna directly to my Fritz!Box?
Yes, that is possible, but it requires a suitable adapter cable. The antenna has an N-female connector, while routers like the Fritz!Box typically have SMA connectors. So you need an antenna cable of the type 'N-male to SMA-male'.
Does the antenna need to be grounded?
For a fixed installation on a building or a tall mast, it is strongly recommended to install lightning protection (e.g., the ALFA ALR06) between the antenna and the end device to protect it from overvoltage.
What does 'Marine Grade' mean?
'Marine Grade' means that the materials and construction of the antenna are specifically designed for use in a marine environment. They are particularly resistant to the corrosive effects of saltwater, high humidity, and strong UV radiation.
Does this antenna improve my mobile phone reception indoors?
Indirectly, yes. If you mount the antenna outside the building and connect it to a 4G/LTE router indoors, it improves the signal the router receives. This can then provide a more stable and faster WiFi signal for your mobile phone and other devices. It does not directly improve the reception of the mobile phone itself.
What is the advantage of an omnidirectional antenna compared to a directional antenna?
An omnidirectional antenna like the AOA-M4G receives signals from all directions and does not need to be aligned with a transmission mast. This is ideal for mobile objects (boats, motorhomes) or when there are multiple transmission masts in the vicinity. A directional antenna bundles the transmission and reception power in one direction, thus achieving higher ranges, but must be precisely aligned.
