Generally, you can install a cell phone signal booster yourself for home use, without needing professional installation[2][4][6]. Self-installation is typically feasible if your home meets certain conditions[2]. These include a home under 5,000 square feet, conventional drywall on wood stud construction, a single interior broadcast antenna, and a main floor with an accessible attic[2].
The general steps for installing a signal booster are[1]:
1. Find the best outside signal[1].
2. Install the outside antenna[1].
3. Connect to the amplifier[1].
4. Install the inside antenna[1].
5. Power on the system[1].
For DIY small business cell phone signal boosters, the installation process is similar to that of home units[6]. However, some situations may warrant professional installation[2]. Complex commercial systems, or larger buildings may benefit from professional installation[2]. If mounting a rooftop antenna is more than you want to tackle, consider hiring a satellite dish installer[2].
