This is a "rough" play for Amateur Radio installations.

Tisha provided EXTREMELY GOOD reference material!

Consider it a PERMANENT fixture on my site!

Bruce, Dave, Dave, Cecil, myself, and others have contributed information.

Roger pointed out the power dissipation being measured in Joules.  Some 
strikes will boggle the imagination!

Bruce spoke of STILL losing some items.  I don't think it IS possible to 
be absolutely safe from a strike no matter WHAT we do.

Do YOUR *BEST*!
