The typical DC-block is just the connectors and barrel with a capacitor in the center conductor path. Loss should be less than 0.5 dB
Surge protectors may be semiconductors or gas tubes typically. In either case, the idea is that voltage between the center conductor and shield must rise to some point above normal operating levels before the device 'turns on' to provide a low impedance path between the center conductor and shield. Loss should be under 2.0 dB.
The gain of a good preamp should be more than enough to accommodate theses in your loss budget.
