Dont know about those particular ones, but I am using a pair of Dressler mast mounted pre-amps with the 847. I supply the 12 V via the coax and they perform beautifully.

Before I destroy these, is anyone using Mirage KP-2 mast mounted preamps with a Yaesu FT-847?

I picked up a couple of them recently, and they came with the control box (which appears to be a bias tee) that supplies 12 volts via the coax line, in order to power them.

The FT-847 can already supply 12 volts up the coax to mast mounted preamps; but I wonder if these Mirage preamps require the use of the control box for some reason.  I would prefer to use the rig to power the preamps, but the manual doesn't mention that option.
