RFI Three-Way 5.8GHz Power Divider

Key Features

Simultaneously connect three devices to the one antenna by splitting the antenna signal
RFI Wilkinson-style power dividers/combiners are used in a variety of RF power dividing and combining applications
Typically used in DAS (Distributed Antenna Systems) for distributing power throughout feeder cable networks
Designed using Wilkinson or N-way styled cascaded broadband binary power splitting or combining techniques offering broadband capability with good splitter output / combiner input, port-to-port isolation.

The input signal is equally split into two output signals, each reduced by 3dB (i.e. halved) due to the 1:2 power division
A small signal loss of 0.5dB is incurred as no RF device can operate at 100% efficiency.
When determining whether you can afford to split your signal, keep in mind that the signal will be halved between each device: the question to answer is - is your signal strong enough?
In very low signal areas it's often advisable to use two antennas instead of a splitter.

While it is possible to sum two input signals with no loss, this can only be accomplished if the input signals are identical in phase and amplitude
When two signals are completely out of phase (180 degrees) the signals will cancel completely, hence the statistical average for two unknown signals is a 3dB combination loss (i.e. reduced by half).
