These bi-directional splitters allow from 2 to 4 inside antennas to be used with a single amplifier. Each inside antenna connection has ≤ 0.4dB signal loss. The full band splitters cover PCS, Cellular, AWS and LTE band systems from 698 MHz to 2700 MHz. These splitters transmit and receive signal and distribute equal amounts of signal sent to two to four interior antennas for similarly sized areas.
