Learn how to install a mobile signal booster for better indoor coverage. Step-by-step installation guide for 4G LTE, 5G, and GSM signal repeaters. Compatible with all major carriers.
Before installation, ensure your signal booster kit includes:
📡 Outdoor Antenna (Directional Yagi or LPDA)
📶 Indoor Antenna (Panel or Dome type)
🔌 Signal Booster Unit (Amplifier)
📏 Coaxial Cables (Usually 10m–20m)
🔩 Mounting Accessories (Brackets, Screws)
⚡ Power Supply Adapter
Use your mobile phone to check signal strength outside your building.
Methods:
Use the built-in signal bars
Or use tools like Network Cell Info, LTE Discovery, or iPhone’s Field Test Mode
📌 Ideal signal: ≥ -70dBm (3–4 bars)
Install the outdoor antenna at the highest point (e.g., rooftop, wall)
Aim toward the nearest mobile tower
Use a directional antenna (like Yagi) for rural or weak areas
Keep at least 10m (30ft) away from the indoor antenna
✅ Mount the antenna firmly, away from metal surfaces and obstacles
Use the supplied coaxial cable to connect the outdoor antenna to the “Outdoor” port on the booster
Ensure secure, straight connection (avoid kinks or sharp bends)
Place the indoor antenna where coverage is needed most (central location is ideal)
Avoid placing near large metal objects or Wi-Fi routers
Connect the antenna to the “Indoor” port of the booster
📌 Panel antennas are better for directional coverage; dome antennas are good for 360° distribution
Plug the booster into a power outlet
Wait for the LED indicators to stabilize (usually green or blue)
Walk around the area with your phone and test signal strength and data speed
📊 Adjust outdoor antenna direction if necessary for best performance
| Tip | Details |
|---|---|
| 📡 Antenna Separation | Maintain at least 10–15 meters (30–50 feet) between outdoor and indoor antennas to prevent self-oscillation. |
| 🔄 Avoid Cable Loops | Do not coil coaxial cables. This may lead to signal loss or interference. |
| 📶 Test Signal Strength | Use a mobile phone or signal meter to find the area with the strongest outdoor signal before installation. |
| ⚠️ Avoid Obstructions | Do not place indoor antennas behind metal walls or near large electronic appliances. |
