Several questions about the circuit protection that using linear power supplies
#2
The primary surge protection is okay, but you will need a good 5v regulator circuit on the output. Preferably current limited; mine uses an adjustable 7805 followed by an extremely fast 400 mA fuse, but that's not optimal.

There is a thread here somewhere that has some good advice and ideas for a voltage regulator.

The fuse is to protect the board components in case, for example, the E-field coax shorts out.
