Well, If you can handle some more info, these ideas may help.   I lost the 
preamps to two fairly expensive Ham receivers before trying these ideas... 
Basically, Nothing will save you on a direct hit, But I installed two zener 
diodes across the coaxial cable
nearest the ground connection outside.  I believe I used 5.1 volt zeners, 1 
watt rating. 
    I wired them in parallel, one with its anode on the antenna hot lead, the 
other with its cathode on the hot lead.. the other leads going to the shield 
of the coaxial cable.  I believe that you could even use a lower value w/ 
Larry's boards (ie 3.3 volt)  without upsetting the circut operation.   I am 
certain that in at least one case they did the job, as one day after a nasty 
storm my receiver would not work with the antenna lead connected.  I 
investigated and found one of the zeners had shorted!  I also use a lightning 
arrester (which is really nothing more than a spark gap)  However it takes 
upwards of a thousand static volts usually to make one of these arc.... You 
can well 
imagine that your sensitive electronic equipment will protect the spark gap 
by conducting first!!   Good luck   Mike.  sw6079@.......   N7ORL
