Gamma Program questions


In your program GAMMA, figure A has dimensions and figure B does not. In figure B, what is the diameter of the Gamma rod, plastic sleeve and tube? They all look bigger than the tube and coax in figure A. For instance, in figure A the tube diameter is supposed to be ¼ diameter of the element, but in figure B there are no dimensions and the tube diameter looks much bigger to accommodate what looks like a bigger rod and a plastic sleeve. So is the rod and plastic sleeve in figure B an actual rod with some kind of insulation plastic sleeve and a gamma tube which looks like it’s the same size as the element , or is it just another coax without the braid and jacket just like in figure A? Maybe a bigger coax? Your help is appreciated.
