The QCP8 Passive Combiner from Contemporary Research is a passive VHF/UHF RF combiner designed for CATV head-end applications. With eight RF inputs and a single RF output, the QCP8 combines multiple RF sources, such as 45 dB out QMOD HDTV modulators and IPTV encoders, with a low 11 dB net loss. It comes with a universal rackmount kit, and vents on each side of the aluminum enclosure allow you to mount the unit side by side with actively cooled QMOD encoder/modulators and the half-rack width provides ample room for a shared rack unit with another 1 RU device.
