I share your thoughts exactly brubble 1. We install the surge suppressor where the cable enters the structure. This is required in the US by the NEC. The radio should have some surge suppressor built in as I was told the Cambium 820 radios have. On a tower installation I bond the shield to the tower near the radio and then where it leaves the tower using grounding kits. The surge suppressor is supposed to protect everything inside the structure like your network equipment and people from high voltages coming down the cable. I am puzzled why the 600SS causes the ethernet connection to run at 100 Base T insted of 1000 Base T. It passes all four pairs. The L033A suppressor I have doesn't cause the Force 200 to switch to 100 Base T. I guess I don't care if the supressor clamps at a little over 30 volts or a little over 56 volts as I am trying to protect what is inside the structure.
