the 3410 at the beginning because you sent me a diagram showing it at the end of the long run
I NEVER showed the 3410 at the end of a long run; always just after the first splitter. I DID show the power inserter at the end of a long run where you might have power, but not the 3410 amp.

The idea is to put an amp as close as possible to the antenna to amplify the signals BEFORE they suffer the coax loss.

You do not need to do electrical wiring if you don't have AC power at the 3410. If you have power at the bottom of the 50' coax, put the PCT-MPI-1G power inserter there. That's where you wanted to put the 3410, so you must have power there.

The power inserter will send power up to the 3410 on the SAME 50' coax that sends the signals down. That is the purpose of the power inserter, so that you don't need to have power at the 3410.

The power up shares the same coax with the signals down.

A power inserter for a preamp works the same way.



It is complicated, and it took me a while before I understood it.

OK?
