News - Why Can’t I Still Make Calls After Installing a Signal Booster?

Installing a cell phone signal booster should eliminate dropped calls and dead zones—but if you’re still struggling to make calls, you’re not alone. Common issues like incorrect setup, mismatched frequency bands, or weak outdoor signals often hinder performance. Fortunately, Lintratek’s tailored solutions—from gsm single/duel/tri/four/five band signal booster to long range fiber optic outdoor repeater—and expert troubleshooting tips can get your calls working seamlessly.

Top 5 Reasons Your Signal Booster Isn’t Fixing Call Issues

1. Mixed-Up BTS & MS Port Connections

Signal boosters have two critical ports: BTS (connects to the outdoor antenna) and MS (connects to the indoor antenna). Swapping these ports breaks the signal flow—your booster can’t capture or rebroadcast calls.

Lintratek’s network mobile signal repeater kits is clear labels (BTS = Outdoor, MS = Indoor) to eliminate confusion. Our installation guide also includes step-by-step diagrams for error-free setup.

2. Insufficient Distance Between Outdoor Antenna & Booster

To avoid “self-oscillation” (signal interference), the outdoor antenna must be at least 10 meters from the booster—preferably with a wall in between. Too little distance disrupts call signal amplification.

Lintratek’s most kits come with 15-meter low-loss cables, giving you flexibility to place the outdoor antenna at the optimal distance. For large spaces, our outdoor 4g signal booster repeater uses fiber transmission to avoid oscillation while covering extended areas.

3. Outdoor Antenna Misaligned with Cell Towers

Your booster can’t amplify what it can’t capture. If the outdoor antenna isn’t pointed directly at your carrier’s cell tower, call signals remain weak.

Lintratek’s directional outdoor antennas (included with all premium boosters) have a narrow beamwidth for precise targeting. We also offer a free signal detection tool to help you locate the nearest tower—critical for maximizing call quality with our lintratek cell phone signal booster.

4. Incompatible Frequency Bands for Voice Calls

Many cheap boosters only support data bands (e.g., 4G LTE) but ignore 2G/3G/GSM bands (900MHz, 1800MHz) used for calls by carriers worldwide.

Lintratek’s multiple models signal booster are pre-tuned to global voice bands, ensuring compatibility with carriers like Airtel, Jio, Verizon, and Vodafone. No more “data works, calls don’t” headaches.
