Default Need help - no signal from TV antenna in the attic

As another poster said first, a 4-way unamplified splitter just will not
work with antenna, althought it will work with cable. This leads to a
solution for the OP: get an amplified splitter OR connect just 1 tv,
which I think they did.


Even though it drops the signal by some dBs it still can work if the
antenna signal is good. It does for me, no amplifier required. Most of
the channels here come from the same repeater and are well equalized,
they remain strong enough for a snow free tuning after one or two
unamplified splitters.


The OP said there was an amplifier at the antenna. How is it
powered? If it is through the coax, the power inserter is missing, and
VERY FEW splitters for TV will pass power from one port to another.
Also, a lot are a single transistor preamp, and will pass a weak signal
without power. Usually 10 to 20 dB down from normal output. Add
another 7 dB loss from a four way splitter, and you can be down to the
noise floor.
