The equivalent diameter of clamps is also covered in Section 9.1 of the Leeson 
text, "Physical Design of Yagi Antennas".  AutoEZ can do the Leeson 
calculations, as shown in this dialog:

For some words to go along with the picture see the end of the first section on 
this page:

The free demo version of AutoEZ includes this feature.  You are more than 
welcome to use it to determine the dimensions and then modify your .ez/.nec 
model as necessary.

AutoEZ info and download:  http://ac6la.com/autoez.html
