A Brief Look at How a Cellular Signal Booster Works
A cell phone booster performs its signal boosting function by the coordinated functioning of its major components: the outdoor antenna, amplifier and indoor antenna. The outdoor and indoor antennas have to be perfectly aimed to ensure good signal reception at your location. As outdoor antennas capture signals from the cellular tower, they have to be directed to the base station.
Directional antennas or yagi antennas do not work 360 degrees, unlike omnidirectional antennas. Thus they have to be perfectly aimed towards the cell tower of your location to ensure strong cellular reception.
Steps In Aiming Yagi Outside Antenna Of Signal Booster
Follow the steps given below to aim an outdoor yagi antenna.
Step 1: Conduct A Trial Assembly Of Booster Components
Before beginning the actual aiming process of the signal booster antenna, you have to temporarily set up the signal booster system by connecting the components by means of cables run through windows or doors. To aim the antenna perfectly, you will need two people. One will stay indoors with a signal testing device like a signal meter, a cell phone in Field Test Mode, or other device. Place the signal testing device 10 or 20 feet away from the indoor antenna and see the readings.
The second person has to be on the rooftop aiming the outside antennas. It is advisable that you mount the antenna on a pole rather than hold it directly.
Step 2: Begin The Aiming Process
- The person on the roof has to aim to one position and hold the antenna in the same position for at least a minute. The person inside the building has to measure the signal strength displayed in the testing device.
- In the next step, rotate the antenna 45 degrees, because yagi antennas work at a 45 degree angle. After it is rotated 45 degrees, hold the antenna in the same position for a minute while the other person records the respective signal strength.
- Repeat this process until you have covered 360 degrees. You will finally have 8 sets of readings.
Step 3: Interpret The Recorded Results
After you are done with recording the signal strength, you have to figure out which direction corresponds to maximum signal strength. If you have taken decibel readings, know that readings close to zero represent stronger cellular signals. Take for instance, the readings -70 and -80. -70 dB indicates better signal strength than -80dB.
After identifying the correct location, find a suitable outside location without any obstacles to mount the antenna.
There are chances for warning lights to show on the booster unit while you are testing the signal strengths. In situations like that, consult the user’s manual to figure out what caused the warning to find an ideal solution.
