Click and drag
Is two two-way splitters, with one output leg of the first splitter split a second time.
Because they do not require an AC or DC power source for their operation; RF signals simply pass through them.
Each output signal power level is slightly less than 50% of the total input level , but both are equal.Their loss are both eaqual.
So the signal can run in several different directions simultaneously.
Is intended to equalize and limit the difference in potential between conductive surfaces.
The input and output ports of passive devices, which reduces the signal's strength.
Taps off a small portion of the input signal while allowing most of the signal while allowing most of the signal to pass through its output port.
