Polyphaser and other lightning arrestors do almost zero for
protecting HF receivers. The problem is they have a breakdown
voltage of about a kilovolt, and the receiver has a failure voltage of a
few hundred volts or less.
The solution I use is relays, that automatically disconnect the
center conductor. The RCS-8V does this, and the relay shorting
bar goes to ground giving excellent protection.
An additional idea that would probably help is some kind of high
resistance leakage or perhaps a choke, that would drain off the
charge that builds up across the series capacitance before it
discharges into the radio.
