EMSplit&trade; Two-Way Splitter for weBoost Drive 4G-X 470510 Wide Band Bidirectional The EMSplit&trade; can be used to split the weBoost Drive 4G-X 470510 internal-antenna signal so that two internal antennas can be used to expand its internal coverage. The EMSpli&trade; can also be used to split the weBoost Drive 4G-X 470510 external-antenna signal so that two external antennas can be aimed in two different directions, a situation that often arises when your system is shared by users served by different cellular service providers. Additionally, when more gain is required by an external antenna, the EMSpli&trade; can be successfully used to combine two directional antennas aimed in the same direction so that your total gain will increase by approximately 3dB (if both antennas are identical). The EMSplit&trade; operating frequency range is 450-3800 MHz. The EMSplit&trade; nominal impedance is 50 Ohm and the connectors are N Female. The connector matching the weBoost Drive 4G-X 470510 inside-antenna side is included (SKU WBT-DRIVE-4G-X-470510-EMS). The EMSplit&trade; can be used in indoors/outdoors environments.
