Hi Even if you are running 50 ohm loads, with 4 outputs, a power splitter is a very real solution. You will be down 6 db on each output. If you start with +13 you will have +7 dbm. Your target devices probably are happy as can be with anything over +3 dbm.
------------------------- If you are worrying about WWVB problems, don’t just look at the cables. Check the connectors as well. BNC’s loose shielding capability much quicker than they get to a high insertion loss. I’ve had a *lot* of grief from them over the years.
