The rear panel features a pair of ANT RF IN A/B inputs, eight BNC outputs (A1–A4 and B1–B4) with DC power distribution, and a separate RF OUT A output for cascading.
The splitter powers compatible EW-D EM receivers and antenna boosters. Use the included NT 12-35 CS power supply and follow local regulations for operating on X-Y frequencies.
