Sebastian,
The bias T is for powering up the preamp if you didn't have the radio
that supplied power.  I have these preamps and work well with my
IC-910 when I use them.
Good Luck,
Dee, NB2F

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.
