Stop the name calling Carl and just leave the people who want to have a 
meaningful conversation alone.

I told you once and I will tell you again, I have both a Handbook and 
Antenna Book, but they are by no means the BIBLE when it comes to this 
stuff.  I don't even see half the stuff in them that you keep referring to 
all the time.

PS:  Never was a CB'er, so I don't know who you were directing your comments 
at.
