Antenna Splitter

The antenna splitter is a passive component that combines multiple GSM/UMTS
channels into one antenna. In 2N

®

VoiceBlue Next, it combines two/four antennae into

one. The antenna splitter is placed in the installation box. It is a passive element – it
has a characteristic signal attenuation value that the antenna connected must
