Polyphaser does make excellent surge supression gear they make it for all
communications services. i.e. Broadcast Radio, television, cell sites,
gov't/military.
Being a ham I use their gear myself expensive but cheaper than a new rig.
Especially since the rig is connected to a structure designed to attract
electromagnetic fields.
