[Carl]

CC used an aluminum tube with a length of RG-213 minus outer jacket and 
shield as one side of the gamma capacitor.

>> Doug,
>> Yes, and while you are at it, change the gamma match to be one made of a
>> coax cable core inside of an aluminum tube as is done with the Directive
>> Systems 50-4 yagi.  I found that the ceramic cap embedded in the feed is
