How come my Muna satellite isn't getting a connection?

I have two identical satellites, with solar panels, batteries and 2 x HG5 antennas.  One is in a KEO and is in view of KSC, the other is in a half muna stationary.  For some weird reason, my KEO sat doesn't seem to be relaying through to my MEO sat.  The Muna sat gets connection when KSC is in view, but doesn't seem to be able to connect to my KEO sat?

To answer my own question, it's because KSC has a stronger transmitter and a more sensitive receiver, so it can transmit farther.  The HG-5s are limited to something like 5,000Mm, Mun is at 11.5Mm
