Just put a 50 ohm load on the second chain.  It would probably be OK left 
unterminated, but best to be safe.

Is it possible to do this?  Can I safely put attenuators on the second chain to 
prevent the card from blowing up? 

My plan is to put an RB922UAGS-5HPacD + SFP in place of a messy fiber box I 
built.  My only concern is that the second chain would need to be handled and 
the dish is only a single polarity.  Replacing the dish/feedhorn is not 
financially realistic.

On a side note, is there a good source for a "female" ST to LC fiber jumper?
