In fact, note that the power inserter is for indoor use only, 115V AC. For long runs, be sure the RG-6 is copper core and not copper clad as there will be some resistive voltage loss of the DC current from the inserter. High-current combiners are needed for antenna connection, if attempted. If possible, use the inserter on an empty cable or single tuner, of course, to input DPP44 #1.
