Channel Master 7777 Pre-Amplifier (UHF/VHF)
This is an excellent mast-mounted pre-amplifier. We have sold hundreds of these and we always receive good feedback on them. These pre-amplifier's are necessary for those extra long cable runs (+100 ft.). Sometimes, it can also help pull in a weak station slightly clearer. View the specifications below to get more information. This preamp has spearate amplification circuits for UHF and VHF. It has the ability to have separate connections for UHF and VHF, or you can opt to use a combined connection. It also contains a switchable FM trap.
