Amazing how the same antenna can produce two different results, 
depending on who makes the test.

It's my understanding a large part of Lindsey's error in giving the 
quad 2 dB gain over a similar boom-length yagi were caused by a 
combination feed system, measurement, and scaling errors.

Yet that article was the start of this entire mess.
