HF shall do no harm neither to the Amel bonding system nor to all connected metals, even if transmitting with high power. It is the DC connection that has to be avoided, and this DC connection will be created by attaching tuner ground to the bonding system. To avoid that this connection has to be "DC separated" by capacitors (HF coupling capacitors, bunch of them soldered together), then the bonding system can be used as a nice HF ground without negative impact.  Only if there is no dynaplate!
