Lengths and positions of the Elements
The given length of the radiator element is from tip to tip, including 10mm spacing for the insulated part.

Updated data 09-Sept-2009 with 12,7mm (1/2 inch) elements and 6mm-elements. The Yagi in the VE7BQH-list has 6mm elements, with 8mm or 10mm the bandwidth is greater and the antenna has slightly more gain, butmore windload.
