Tired of dropped calls and slow data when you are on the move? The Ubox ANN-MB3 antenna is a compact, high-performance antenna that fits inside your device and keeps you connected. It works on the 698-960 MHz and 1710-2690 MHz bands, so you get reliable voice and LTE signals wherever you go. If your current antenna is weak, you will notice better signal strength and fewer interruptions with this upgrade. Installation takes only a few minutes and does not require any special tools.
Ubox ANN-MB3 antenna
Many users complain that their phone or IoT device loses signal in crowded places or near windows. A weak antenna turns a simple task like checking email into a frustrating experience. The Ubox ANN-MB3 solves this by offering a 3 dBi gain, omni-directional pattern and a low VSWR of 2.0, which together deliver a stronger, more stable link on both 4G and older networks. It is compatible with most LTE modules that use a u.FL antenna port, making it a versatile upgrade for many brands.
Usages of Ubox
The antenna can be glued to the back of a smartphone, a Raspberry Pi LTE hat, a drone telemetry board or any small enclosure that needs better reception. It works for mobile phones, portable routers, vehicle trackers and home-automation hubs. Because the connector is a u.FL plug and the cable is only 100 mm long, installation is quick and does not interfere with other components. For outdoor installations you can protect the adhesive with a small waterproof cover to keep performance stable in rain.
Benefits
- Stronger signal reduces dropped calls and improves data speed.
- Omni-directional pattern keeps connection stable no matter how you turn the device.
