Hello Piet,

The real question to ask is what the current draw of the ARR mast mounted
preamplifier with internal relays will be, and if the Kenwood TS-2000 
can source that current.

Others can comment as to the Kenwood's capability, but you can measure 
the current draw of the ARR.

I suspect the Kenwood may not be rated for that current and either an
external DC injector is needed to put DC on the coax or other wiring 
direct to the ARR is needed.

A sequencer could be used to source the current and under MIC PTT control
would properly turn it off during TX.
