Not really DSP, but I thought that some of the HAM guys on this forum may have seen this before.

Have you every noticed when lighting strikes it causes the RF signal in a coaxile to completely drop offline for a short moment? 

Why does this happen?

How can this be prevented?

Thanks!

Hi.

Can you give us more details of exactly what you mean by "RF signal in a coaxile to completely drop offline"?

lightning arrestor "fuse" breaks?
