MoCA issue with 3 Way Splitter

I recently purchased a Bolt and 2 Minis. After some research and initial issues I ordered a Holland POE filter and a Holland 3 way splitter. The splitter is unbalanced.

Last night I configured my system as follows:

Antenna -> POE Filter -> Splitter In
Splitter -3.9 Out -> Bolt
Splitter -7.7 Out -> Tivo Mini #1
Splitter -7.7 Out -> Tivo Mini #2

With this configuration I found that the Mini would bind to the network for 30 to 60 seconds and then drop. Bind and drop, bind and drop.

I replaced the the unbalanced 3 way splitter with a 2 way splitter as follows and everything worked as expected.

Antenna -> POE Filter -> Splitter In
Splitter -3.5 Out -> Bolt
Splitter -3.5 Out -> Tivo Mini #1
Ethernet -> Tivo Mini #2

Is the unbalanced splitter causing my issues or is the signal loss across the entire configuration causing my issue?

Next step is going to be to use a balanced 3 way to see if that solves the problem so I can run the entire system on Coax.
