Great... I must be searching with my eyes closed!

I believe I see an error in "Fig. 1" in that document. The text to the
left states you need a" Copper pipe with a diameter of 10 mm and a
length of 1480 mm". Correct. However, the diagram claims a length of
1480 mm from the top of the antenna to the top of the sleeve. Wrong!
That length on the figure should be 975 mm and/or the diagram should
have been drawn to show that the 1480 mm length is from the tip to the
_bottom_ of the entire assembly.

Nicely done document.
