Out of the dead zone – Into a stable connection
You know the feeling: inside your camper, workshop, or technical cabinet, the 4G connection constantly drops. The ALFA AOA-4G-2ACM solves exactly this problem. Instead of using the weak signal indoors, you mount this antenna directly on your outdoor router or enclosure and get the strong, unfiltered 4G signal from outside. The result is a significantly more stable and often faster connection that you can rely on.
Built to last: Robustness meets performance
Where other Antennas give up in wind and weather, the AOA-4G-2ACM is just getting started. Its housing is made of solid, UV-resistant fiberglass. This makes it impervious to sunlight, rain, ice, and extreme temperatures. This robust 4G antenna for motorhome and industrial applications is the perfect choice for anyone looking for a durable and maintenance-free solution for continuous use. The direct, vibration-resistant mounting makes it the first choice for mobile setups in the Yacht / Camper / Motorhome sector.
Plug & Play: The art of simple installation
Complicated installations are a thing of the past. The AOA-4G-2ACM is a 4G Outdoor Antenna for direct mounting. Thanks to the integrated, solid N-connector, you simply screw it onto the corresponding N-jack of your device by hand. No additional cable, no shaky bracket. This type of mounting is not only extremely stable but also minimizes signal loss. For routers with other connections (e.g., SMA), you will find suitable Coaxial Pigtails with us.
360° Freedom: The advantage of the omnidirectional antenna
Forget the tedious alignment with a distant transmission mast. As an omnidirectional antenna, also known as a radiator, the ALFA 2dBi Omni 4G Antenna receives mobile signals equally well from all horizontal directions. This is ideal for urban environments with multiple transmission masts or for mobile applications where the orientation constantly changes. Simply mount it and immediately enjoy the best possible reception at the respective location.
Strengths & Notes at a glance
- Pro: Extremely robust fiberglass construction for harsh outdoor use.
- Pro: Fully weather and UV resistant (-40°C to +80°C).
- Pro: Easy and stable direct mounting thanks to integrated N-connector.
- Pro: Omnidirectional 360° characteristic requires no alignment.
- Pro: Comprehensive frequency support for 2G, 3G, and 4G.
- Pro: Ideal for vehicles, boats, M2M, and outdoor Enclosures.
- Note: The antenna gain of 2 dBi serves to stabilize, not to amplify extremely weak signals over long distances.

Frequently Asked Questions (FAQ)
Does the AOA-4G-2ACM fit every 4G Router?
No. It only fits Routers or systems that have an external Antenna connection in the form of an N-female connector. For common Routers with SMA or TS9 connectors, a suitable Adapter Cable (Pigtail) is required.
Is this Antenna guaranteed to improve my 4G reception?
It improves reception in most cases, especially when the Antenna is mounted outside a building or vehicle where the signal is stronger. The low gain of 2 dBi primarily serves to stabilize the signal and overcome attenuation through walls. In cases of extremely poor reception, an Antenna with a higher dBi value is necessary.
Is the Antenna suitable for use on a vehicle or boat?
Yes, absolutely. Its robust fiberglass construction and direct, vibration-resistant mounting make it ideal for use on vehicles, motorhomes, boats, or M2M (Machine-to-Machine) applications.
What does "omnidirectional" mean?
Omnidirectional means that the Antenna receives and transmits signals equally well from all horizontal directions (360°). Therefore, you don't have to align it with a specific transmission mast, which greatly simplifies installation.
Do I need a Lightning Protection element for this Antenna?
If the Antenna is the highest point on a building or mast, Lightning Protection (surge arrester) is strongly recommended to protect connected devices like the Router from damage due to lightning strikes. This is connected between the Antenna and the Router cable.
