[Amps] Hmmmm...Legal limit boiled the oil in the cantena

[Jeff Blaine AC0C]

Bill,

There has to exist, at a minimum, a DC blocking cap of some kind.  I may 
have missed some part of the conversation but I would guess that must be the 
case...

Of course, after looking at bigradios.com web site just now, maybe some guys 
may consider 10KV or whatever sitting on the antenna elements an acceptable 
situation for the 10 seconds or whatever it is that the B+ is applied to 
these flame throwers.
