Your Anchor for Stable Internet at Sea and on Land
Do you know the feeling? You're out on your boat or enjoying the freedom in your motorhome, but the internet is slow or constantly breaking off. This is often because the metal shell of your vehicle shields the mobile signal. The ALFA AOA-M4G is the professional solution. As a powerful 4G Omni-Directional Antenna for Motorhome and boat, it brings the signal from outside to inside. Simply mount it on the mast, connect it to your 4G router, and finally experience a stable and fast connection that reliably connects you to the digital world.
Built to Last: Marine Quality that Convinces
The term 'Marine Grade' is not an empty promise here. The AOA-M4G was specially developed for the harsh conditions at sea. Its housing made of solid, UV-resistant fiberglass (GRP) and stainless steel components are absolutely impervious to saltwater, spray, and constant sun exposure. This 4G Antenna for Boat and Camper is an investment in longevity and reliability that will accompany you on your travels for many years without losing performance.
360° Freedom: Reception Without Compromises
While directional Antennas must be precisely aligned with a transmission mast, the AOA-M4G as an omni-directional radiator offers you maximum flexibility. It receives signals from a 360° radius, making it the ideal choice for mobile applications. Whether your boat is rocking in the wind or you park your camper at a new pitch – the Antenna continuously ensures the best possible reception, without you having to lift a finger. Simply install and permanently benefit from a better signal.
System Integration Made Easy
The ALFA AOA-M4G is equipped with a professional N-Female connector, which ensures a secure and low-loss connection. It is the perfect complement for outdoor modems such as the ALFA Tube-U4Gv2, but can also be easily connected to a variety of other devices. For connection to common routers such as Teltonika 4G / 5G Routers models or a Fritz!Box, you only need a suitable Antenna Cables (e.g., N-connector to SMA-connector). This way, you seamlessly integrate this high-performance antenna into your existing Network and elevate your mobile internet access to a new level.
Strengths & Notes at a Glance
- Pro: Extremely robust and weather-resistant thanks to marine-grade fiberglass construction.
- Pro: Ideal for mobile applications (boat, motorhome) due to 360° all-round reception.
- Pro: Covers all relevant European 2G/3G/4G frequencies for high compatibility.
- Pro: Significant improvement in signal strength and stability compared to internal Antennas.
- Pro: Professional N-connector for a secure and low-loss cable connection.
- Note: For MIMO systems (e.g., Fritz!Box, Teltonika), two of these Antennas are required.
- Note: The gain is moderate; in extreme fringe areas, directional antennas may be superior.

Frequently Asked Questions (FAQ)
Is the ALFA AOA-M4G suitable for 5G?
Partially. The antenna covers the frequency ranges 698-960 MHz and 1710-2700 MHz. It therefore supports some 5G bands that are shared with 4G in so-called "Dynamic Spectrum Sharing" (DSS). However, it does not cover the newer, high 5G frequency bands (e.g., 3.5 GHz) that are necessary for maximum speeds.
Do I need one or two AOA-M4G antennas for my MIMO-Router?
For optimal MIMO performance, you need two identical AOA-M4G antennas. These must be mounted with a certain distance (ideally >50 cm) and often with different polarization to fully exploit the technology's potential.
How is the ALFA AOA-M4G antenna mounted?
Which cable do I need to connect the AOA-M4G to a Fritz!Box?
You need a high-quality, low-loss coaxial cable with an N-connector for the antenna and an SMA connector for most 4G routers like the Fritz!Box. The length should be as short as possible to minimize signal loss.
What does "Marine Grade" mean for this antenna?
"Marine Grade" means that the materials and construction are optimized for harsh marine conditions. This includes the use of corrosion-resistant fiberglass, a waterproof seal, and a robust design that withstands strong vibrations and wind loads.
