The High-Performance Solution for your 4G Outdoor Antenna
In locations where internal reception of your router fails due to massive walls or long distances, the JARFT J4GMB-14-DOMPA shows its full strength. As a focused 4G directional Antenna, you mount it where the signal can arrive unhindered – ideally on the roof or on a high mast. Through strong physical focusing of the radio waves, the available energy is directed exactly to your device, noticeably optimizing your WLAN throughput and latency times.
Maximum Compatibility for all Providers
Whether you use a Speedport, a Gigacube, or a Teltonika router – this Antenna is universally applicable thanks to its multiband capability. You don't have to worry about the frequency used at your location, as the antenna automatically covers the optimal range. Since all major European providers are supported, your investment remains protected even if you change your Network operator.
Easy Installation with Variable Cabling
Fittingly, you can choose a high-quality twin Antenna Cable in your desired length (2.5m, 5m, or 10m). The N-connectors fit the antenna exactly, while the SMA-connectors are the standard for almost all 4G routers. Thus, you instantly transform your weak signal into a stable broadband connection. Generally, the rule for planning is: the shorter you keep the cable, the more of the 14 dBi gain arrives directly at your router.
Robust Hardware for Extreme Conditions
The housing of the antenna is made of UV-resistant PVC, while the back is made of rust-proof stainless steel. This robust construction allows for use even under extreme weather conditions outdoors. Thanks to the integrated DC grounding (DC-Ground), the antenna also offers solid basic protection. With the mounting kit included in the scope of delivery, attachment to masts between 30mm and 50mm in diameter is a breeze.
Strengths & Notes at a Glance
- Pro: Enormous gain of 14 dBi for maximum ranges.
- Pro: Large-scale 47x31cm panel for highly efficient reception.
- Pro: Corrosion-resistant thanks to the stainless steel backplate.
- Pro: Integrated DC grounding for increased basic safety.
- Pro: Variable twin cable sets (up to 10m) can be ordered directly.
- Pro: Weatherproof housing for permanent outdoor use in any climate.
- Note: The antenna must be aligned very precisely due to the narrow beamwidth.
- Note: When using with mobile cubes, a TS-9 adapter from our range may be necessary.

Frequently Asked Questions (FAQ)
What are the benefits of a 4G Outdoor Antenna?
By mounting outdoors, you prevent walls and windows from attenuating your signal. You capture the signal where it is strongest.
Does the JARFT J4GMB-14-DOMPA support all networks?
Yes, it covers all 4G frequencies used across Europe (800, 1800, 2600 MHz) and works with all providers.
Which cable length is optimal for the 4G directional antenna?
Generally: the shorter the cable, the better! Choose a length that allows you to reach the router without unnecessary signal loss.
Is the antenna 5G compatible?
Yes, it covers all 5G bands below 2.7 GHz, which is perfectly sufficient for current signal boosting in most locations.
Do I need an adapter for a Gigacube or Speedport?
Most stationary routers have SMA connectors. If you use a mobile cube with TS-9 ports, you can find fitting adapters in our shop.
How do I align the antenna precisely?
Align the antenna with a clear line of sight to the nearest cell tower. Your provider can give you information about the exact location.
