I am resending this as it didn't make it to the list the first time.
>From the DX Eng manual "Lightning protection is excellent in the relay
system. There is never an ungrounded path for lightning, regardless of
how you configure internal jumpers".
I suggest you email DX Eng. for their advice with your antennas. For
example with half slopers the unused ports should be left ungrounded.
You will be pleasantly surprised with their fast response.
