The Channel Master TITAN television antenna boosters (preamplifiers) will amplify
digital and HD signals received by your antenna. Preamplifiers are also used if you
anticipate distributing your signal with a digital splitter to multiple outlets throughout
your houses, as splitters reduce the signal strength available at each output.

The CM-7777 and CM-7778 are mast mounted amplification units with indoor power
supplies that connect via coaxial cable. The preamp and the power supply can
withstand temperatures up to 140° F. They feature all metal, outdoor rated housing.

Power Inserter, Power Supply, 6' Coaxial Cable Jumper, Hardware, & Instruction
Sheet Included.
