Preamp versus Lightning Arrestor


Hello men.

I have a couple questions regarding my lightning arrestor. I have the TII212.

1. Should I just forget about it and use a simple ground block instead?

2. What is the signal loss with this device?

3. Should the device be installed *before* or *after* the preamplifier, in the signal flow? Would you install a ground block in the same place in the signal flow?

Thank you fellows!
1. Use both, it you'd like to improve the protection of the pre-amp. If so, mount the SP at the input of the amp. If not, use it in place of the grounding block that is required at or near the cable ingress point.

2. Minimal, unless it blows.

3. See 1 above.
