Radome material: ABS Antenna weight:1.91lb FAQ: Question: After installing booster, signal not be very good, indoor signal coverage very small. Solution: 1. adjust outdoor antenna's location and direction. 2. check whether cable connected well. 3. put more higher receiving antenna's position, which can receive more good signal. 4. change another bigger power booster. 5. change another high gain receiving antenna. Question: Cellphone signal full bar, but communication quality bad. Solutions: Too closer distance of indoor and outdoor antenna, need more separation far distance away between antennas. Question: After installing booster, signal not good, but even worse than before. Solutions: Too closer distance of indoor and outdoor antenna, need more separation far distance away between antennas.
