One of the best, if not the best, resources for building a full sized 40m 3
element Yagi is ON4UN's text "Low Band DXing"
Using machined reducers to step down from 2" OD center element sections to 1.5"
OD (which then tapers to 0.5" OD) is an excellent idea.
6061-T6 is the material of choice.
Have fun with your project! It will bring you great satisfaction when on the
air.
Best regards,
Scott W3TX
