Distribution Amplifier, 8-way, 4db, 50 to 1002 MHz, with return path, Channel Master CM-3418

ITEM: 3418

Channel Master distribution amplifiers, manufactured by Channel Master’s former parent company, PCT International, one of the leading manufacturers in the cable telecommunications industry, will boost your digital TV and HDTV signals, increasing their overall signal strength. They have a miniature design which will give you more space to relieve congested installs when space is at a premium. Channel Master distribution amplifiers are professional grade and meet stringent US and international standards, including those developed by the Society of Cable Telecommunications Engineers (SCTE), who creates international standards for many TV signal distribution products. Channel Master distribution amplifiers can be used in HDTV, CATV, off-air, analog and digital RF distribution applications where high performance and reliability are required. The CM 3418 is a high quality miniature eight output digital TV amplifier with passive return, which means the distribution amplifier does not have any amplification for signals in the return path frequency range (5-42 MHz). This frequency range is used in cable telecommunications networks to allow cable modems and set top boxes to communicate back through the cable network. Passive return amplifiers are the most commonly used in-house distribution amplifiers by cable operators. Channel Master distribution amplifiers have precision machined F ports (conforms to SCTE standards) that are gold plated with beryllium copper construction to provide optimal distribution and amplification of your RF signals.

Works for my X1 boxes
By Jake
I previously have the 2-way version of this and had one leg going straight to a problem TV over 50' of RG6 from a split, and the other leg to a high quality splitter that fed 3 other TVs. When I upgraded to xfinity X1, the box on its own leg kept working, but two others didn't. (The last TV just uses a Comcast digital adapter...) I swapped the two-way model out with this one (got the 8 instead of the 4 for expandability). While I was installing it I had both new problem TVs on and within earshot - and both frozen... I make all the connections then plugged in the power and voila - both sprang to life!
