There's a lot of information in the literature and it's becoming more
difficult to ascertain what is valid and accurate.  In the past week, I have
discovered as much MISINFORMATION concerning the performance of quads v.
Yagis as I have with respect to transmission line theory.  I suspect that
much of the inconsistency through the years can be attributed to a lack of
standardized and generally-accepted measurements and procedures.  What
assurance do we have that the W2PV information valid?  Further, what makes a
consensus in this case?

>Are you sure that John B A T T I N, K9DX, uses quads?

No, I always make a point of stating a fact when I'm not sure (?).  Yes John
B A T T I N, K9DX was using his Cubex Mantis quad when I worked him last
Thursday night on 40-meters while he was running 1KW.  Need further proof?
Multiple images of his Mantis installation are available at:
