Three-way splitter is compatible with digital broadcast television, digital cable television, off-air antennas and RF distribution from 5 to 1000MHz. Zinc plated, die-cast housing with precision, machined ports ensure 130dB isolation against RF leakage. 360ø insert pins provide maximum signal transfer maintaining a distortion free signal for digital transmission. PC board technology eliminates low frequency hum and provides a clean return path for data from the cable box or cable modem. Weather sealed ports resist moisture to 30PSI that can degrade picture quality and affect the performance of the splitter.
