If you're doing beam forming, the "one amp driving multiple loads" approach is probably going to do the best and most stable job of getting what you need. And all your loads should be identical, not some mix of different makes/models. But you will need to find an amplifier that can deliver the

I am working in a project that requires me to have very similarly phased 10mhz references (beamforming). Previously I just used splitters for 10MHz but now I am graduating to a distribution amplifier. Looking for suggestions/recommendations and what I should consider. Distributing a Fury or a
