To find the best outside signal for your cell phone signal booster, consider these factors:
* Signal Strength Measurement: Walk around the outside of your home or building to test the signal strength[2][6]. The area with the most signal bars on your phone is generally the best location for the outside antenna[2]. Keep in mind that signal bar measurements can be subjective[2].
* Directional Antennas: Use a directional antenna to optimize the Signal to Interference plus Noise Ratio (SINR)[3]. For best results, spend time aiming the outdoor antenna correctly[3].
* Antenna Placement: Install the outside antenna in the area where you detected the strongest signal[6][8]. This is often on the roof[8].
* Antenna Gain: Select an antenna with an appropriate gain for your needs. Higher gain antennas are better for areas with weak coverage, while lower gain antennas are better for areas with strong signals[4].
* Single Carrier Boosters: If you only need to boost the signal for one carrier (AT&T, Verizon, or T-Mobile), consider using a single-carrier booster with a directional antenna. These can have a higher gain (up to 100 dB) and can significantly improve signal strength in weak signal areas[1][3]. The Cel-Fi GO X is a recommended option[1][3].
* Line of Sight: If you have a direct line of sight to the cell tower, consider using a grid parabolic antenna for even greater gain. Be sure to check the frequency support and be cautious of exaggerated gain numbers[3].
* Multiple Indoor Antennas: If integrating multiple indoor antennas, ensure that there is enough signal to feed them all[5]. Using a splitter with multiple indoor antennas doesn’t increase the overall coverage area, but distributes the signal to multiple areas[5].
