[Elecraft] Avoiding costly lightning damage to your radios gear

[ab2tc]

Hi,

It's a dead short circuit for DC and low frequencies thanks to the SWR
bridge (it has a voltage transformer directly across the antenna terminals).
There seems to be different opinions on what is meant by "static". To me it
means a slowly varying DC voltage caused by static buildup in the clouds
during or before thunderstorms. The K3(S) is perfectly protected against
these. Some people include the transients that are caused by actual
lightning strikes nearby in the definition of "static". The K3(S) is not
protected against these as they have very strong high frequency content. For
these extra protection is needed as discussed several places in this thread.
I have a number of Alpha-Delta switches in my antenna system and they have
gas discharge tubes, but frankly I have no idea how effective they are.
