If you need an endorsement, I believe this antenna was the choice of the
2014 WRTC. It was made originally by Cycle 24 but later the designer hooked
up with JK to do the builds.

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.

i would disagree: the dBi numbers seem in line with other trapless 2-el
designs, such as the C3 or XR3.
They’d be way high if they were quoted as dBd numbers, but take off the,
what, 2.4 dB, to get to dBd and 4 dB and change sounds reasonable. At
least, way more reasonable than, say, 8 dBd that some three-element
trapped tribanders pretend to have...
