Your Signal Booster: 14dBi for Maximum Range
Do you live in a rural region or is your office shielded by thick walls? Where 4G reception is weak, the JARFT J4GMB-14-DOMPA shows its full strength. With an extremely high gain of up to 14dBi, this Antenna effortlessly bridges long distances to the nearest transmission mast. The narrow beamwidth of only 30° precisely bundles all the energy in one direction. While this requires precise alignment, it rewards you with a stable and fast connection you haven't experienced before. It's the perfect 4G Outdoor Antenna MIMO for rural areas.
MIMO Technology in Perfection
This Antenna is more than just a signal booster. Inside, two perfectly coordinated Antenna elements optimally support the 2x2 MIMO process of your 4G Router. By using two parallel data streams (vertically and horizontally polarized), not only does the theoretical speed double, but the stability of your connection also noticeably improves. You simply connect the two N-sockets of the Antenna with a Twin Antenna Cable to your Router and immediately benefit from better data throughput – ideal for streaming, home office, and online gaming. This Panel Directional Antenna is a true high-performance component.
Built for Eternity: Robust Outdoor Construction
The J4GMB-14-DOMPA is designed for continuous outdoor use and withstands all weather conditions. The housing (radome) is made of impact-resistant and UV-resistant PVC, which won't become brittle even after years in the sun. The crucial component, however, is the solid stainless steel backplate, which guarantees absolute corrosion resistance. Whether storm, rain, snow, or extreme temperatures from -30 °C to +75 °C – this weatherproof 4G Antenna with stainless steel bracket consistently delivers reliable performance.
Universal Compatibility and Easy Mounting
Don't worry about compatibility. The JARFT Antenna covers all relevant 4G/4G frequency bands in Europe (800, 1800, and 2600 MHz) and therefore works with any provider and any 4G Router that has external Antenna connectors. Mounting is straightforward on a mast (30-50 mm diameter) or directly on a wall, thanks to the included mounting bracket and pipe clamp. This also makes it an ideal High-Performance Directional Antenna for FritzBox 4G Routers and models from other manufacturers.

Frequently Asked Questions (FAQ)
Do you need one or two of these Antennas for your 4G Router?
No, you only need this one Antenna! Its housing already contains two powerful antenna elements (2x2 MIMO). You simply connect it with an antenna Cable directly to both antenna ports of your 4G Router, and you're ready to go.
Can I use the Antenna even if my Router has TS-9 or CRC-9 connectors?
Yes, absolutely! The Antenna features professional N-connectors. To connect it to your Router, you'll just need a suitable Antenna Cable and small adapters (known as Coaxial Pigtails) that convert the connection to TS-9 or CRC-9. This way, everything fits together perfectly.
How do I find the right cell tower and perfectly align the Antenna?
It's simple! You can find the nearest cell tower using your provider's online maps or specialized Network coverage apps. For perfect alignment, log into your Router, check the signal values, and then move the Antenna in very small increments until you find the strongest signal for your connection.
Does the length of the Antenna Cable make a big difference?
Yes, a huge one! The golden rule is: as short as possible, as long as necessary. Every extra piece of cable weakens the signal a little. A long cable can negate some of the strong 14dBi gain before the signal even reaches your Router.
Is this Antenna also compatible with 5G?
No, this Antenna is a specialist for 4G and optimized for frequencies up to 2700 MHz. Typical 5G frequencies are higher. So, if you want to use 5G, you'll need a specific 5G Antenna.
What does 'DC-Ground' mean, and do I need to ground the Antenna separately?
'DC-Ground' is a clever feature that internally protects your Antenna from static electricity. Important for you: If you mount the Antenna on the roof, this does not replace proper Lightning Protection grounding. For maximum safety, you should have the mast grounded by a professional.
