Medusa and CN Pulse

Hi all, just getting it by a winter storm and I have one site that has a 450m on the tower receiving sync from a tx 2012r-p and I keep losing sync to the medusa… have 4 epmp 3000 antennas good to go not losing sync, they are set to CMM and they do not go down. also have a gps puck attached to the tx switch as well. Any help insight would be great! Thanks!

If my cnpulse goes down shouldnt the gps puck pick up the slack?
