[RFI] Comparing Lightning Arrestors?

[myles landstein]

While I understand what you are saying,  "Nothing will protect from a direct hit'  , and of course  recommend disconnecting ...

But  I disagree,  their have been  stations both amateur and commercial  that have survived several direct hits   ,  they were simply designed  properly.  

Doesn't mean they  can't  ever be damaged,  but with some well designed lightning protection  you can save your gear (and perhaps yourself) from damage on those days disconnecting has been overlooked.

Proper protection will cost   more then 5$  but not a ton of money vs   the  havoc lightning  can cause,  a good  investment.  don't give up

cheers

Nothing will protect from a direct lightening strike except for disconnecting everything, including the ground OR a superior grounding installation such as at <http://www.w8ji.com/station_ground.htm>.  Disconnecting everything is what I do.
