The Delta 240 2 element 40 meter Yagi is the new generation of shortened 30 and 40 meter Yagis. The 40 meter elements are about 39’ long, or 59% of full size and the 30 meter elements are 24' long, a bit more than half size. The elements utilize an extremely hi Q (>800) loading coil on each half of the element. The Delta 240 can be placed within about 1-2 meters of other HF dipoles and Yagis, without destructive interaction. If you have a tribander, such as a C-3, C-19XR, C-31XR, or a 5-band Yagi such as the XR-5, the Delta 240 can be placed within a few feet on the same mast.
