I don't know much about these things but I think you're saying at the end of your post is that, regardless of whether I use amplifiers, running separate RG6 cables from the new aerial to each TV should provide a much better signal to each than splitting a single cable to feed them. |
From the description, I think the powered bit is actually a power over antenna cable system, which probably has to connect to the masthead amplifier/splitter at port 1.
The other ports also provide 10dB gain, so if you had separate runs, each has 10dB gain, while if you use a single run and a splitter that loses 6dB, then you only have 4dB gain. also, a splitter between the power unit and the antenna may not properly pass the power, depending on the design of splitter.
The advantage of a masthead amplifier (in weak signal areas) is that it gets to work on the signal before any has been lost by the cable length, making a big difference if the signal is borderline.
