Why use a DC blocked protector? The DC blocking will do next to
nothing for lightning protection if it passes HF signals without a
SWR bump. Lightning is a time-varying pulse, not DC. The DC
energy content is actually not very high in lightning.

Then try an Ameritron RCS-8, but remember you have to suitably
protect or better yet disconnect the cables if you want real lightning
protection.
