Signal Booster, designed to solve these pain points for you.
Why Choose Our Tri-Band Amplifier?
This device is more than a signal repeater—it ensures your communication quality. It supports bothGSM 900 MHz(primarily for 2G voice in rural and suburban areas),
DCS 1800 MHz(2G/4G LTE mainstream bands in {0}) andWCDMA 2100 MHz(3G data and HD voice). This means that no matter which phone you use
It delivers stable signal support across all network types.
Intuitive LCD Smart Monitoring
No more guessing! The front of the device features a high-definitionLCD displayDuring installation, you can view the real-time received signal strength (downlink) of the outdoor antenna and the indoor
Transmit signal strength (uplink). By observing the signal indicator on the screen, you can easily adjust the outdoor antenna's orientation to find the optimal signal point, even for
Easy installation for non-professionals.
Industrial-grade heat dissipation and stability
The silver aluminum chassis delivers a modern, minimalist look while acting as a natural heat sink. Combined with an efficient internal circuit design, it ensures the device runs continuously 7x24 hours.
Maintains stable performance under load without thermal throttling or crashes.
Wide range of applications:
Home/Villa:Eliminate indoor signal dead zones caused by thick walls.
Basement/Parking Garage:Keep underground spaces connected.
Factory/Warehouse:Ensure workers maintain connectivity via walkie-talkies and mobile phones across large areas.
Hotel/Restaurant:Enhance customer experience and avoid negative reviews due to poor signal.
❓ 3. Frequently Asked Questions (FAQ)
Q1: Which countries and carriers is this signal booster compatible with?
A: This device supports three frequency bands (900/1800/210 MHz), a globally compatible combination. It works in most regions across Europe, Asia, Africa, Australia, and more.
The regional carrier.Please confirm before purchase that your local mobile network bands fall within these three ranges., we can assist you with the inquiry.
Q2: Can I install it myself, or do I need a professional?
A: You can install it yourself. We provide a complete plug-and-play kit (outdoor antenna, indoor antenna, and cables). Just follow the instructions to align the outdoor antenna with the base station.
-> Connect to the host -> Place the indoor antenna in the area you want to cover. The LCD screen will help you confirm that the signal has improved.
Q3: Do signal boosters emit radiation? Are they safe?
A: Very secure. In fact, using a signal booster actually enhancesReduceYour phone's radiation. When signal is poor, the phone transmits at maximum power to find a base station;
amplifier, allowing the phone to connect to the indoor antenna at very low power. This extends battery life and reduces radiation. The device operates at only 100mW, well below
National Security Standards.
Q4: Is this device useful if there's no outdoor signal at all?
A: Signal BoosterWorks by "amplifying" existing signals, not "generating" them. If there is absolutely no outdoor signal (0 bars), the amplifier cannot function.
It requires at least a weak outdoor signal (even just 1 bar) to amplify.
Q5: What if the 15-meter cable is too short?
The standard 15-meter feeder cable meets the needs of most villas and buildings. For longer distances, we offer custom low-loss coaxial cable solutions.
Alternatively, we recommend installing the outdoor antenna on a windowsill or balcony closer to the main unit.
