In wireless kits cable is placed between the external antenna and amplifier, and between the amplifier and the internal antenna. For repeater kits where you can customize the cable length, please see our Repeater Kits page. You can also use coaxial cable to attach your phone directly to a cellular antenna. In this case an adapter cable is also needed. Remember: Coaxial cable attenuates the cellular signal. In order to improve performance use the smallest cable length possible.
