Tom, N6BT in his book Array of Light, goes to great lengths to specify the 
parameters associated with gain specs.  Good stuff, well known.
But then he goes on to claim that his 2 element designs will beat any trapped 
tribander regardless of size!  Who knows?  But It doesn't appear as if Ken of 
JK Antennas has done anything to distort the gain figures right from the highly 
respected NEC4 model from which his antennas are built.  What else could you 
ask for?  No wild claims, no marketing hype.  Isn't this what we've been 
demanding of antenna manufacturers for 50 years?

By the way, sorry that I am unable to delete the text below.  Hotmail does not 
give me an option that I can find.
