Microlab Dx-28 series 2/3/4 way reactive Power Splitters have been designed to evenly split high power cellular signals with minimal reflections or loss. All joints are moisture sealed with o-rings to meet IP67 rating. The mechanical shape allows ease of mounting to the wall. The wide frequency range allows use in networks where TETRA and n78 5G wireless service are distributed to multiband antennas and leaky cable systems. With few solder joints and an air dielectric, the loss has been minimized and reliability enhanced.

See Dx-83FE series for USA 5G NR n77 support.
