I'm running coaxial burried in conduit out to my workshop that is
approximately 180 feet from where the cable enters the house. I've been told
that I will need a signal amplifier.

Where does this amplifier hook up to ?? At the beginning of the run or can
it be installed at the end ?? Does this amplifier need to be plugged into
an outlet ?? If this needs to go at the beginning of the run and powered
up, how can I do this if the splitter is mounted to the fascia on the
outside of the house ??

Thanks,
