If I already have a cell signal booster system for one carrier, can I add a second system for another carrier?
Yes, you can have two different cell phone carriers. This will, however, require installing a second outside donor antenna, additional inside broadcast antennas, the booster, and cabling.
It’s often simpler to use your existing antennas and cables, and just replace the booster unit itself. As long as your existing antennas and splitters are wideband-compatible (698–2155 MHz), replacing just the booster unit is relatively easy.* If your antennas operate only on older, narrower frequencies, replacing them is also fast and inexpensive. Most of the time, your existing coax cable will work just fine with a new booster system.
If you do not have access to the existing single-carrier booster—for example, someone else owns the system and will not allow you to modify it—then you’ll need to install a separate, channel-specific cellular amplifier for the new carrier frequencies. Channel-specific amplifiers are tuned for specific carrier frequencies, and require more time, money, and effort to install. They also require special approval from the carriers themselves. You may not have two different systems in the same building that use the same frequencies, though.
* Per FCC regulations
, as of , all consumer signal boosters sold in the United States must be sold as a kit, with antennas and cables. This means that, in most cases, replacing a cell signal booster requires us to sell you antennas and cable along with the new booster.
