Pictures and some details of a multiband dipole antenna
Added the 160m coil on the end. Had to add to the 80m leg. It went from 59″ to 97″.
The 160 leg is 56″ long and made of 14 gauge insulated wire. The coil is 2″ O.D. and 10″ long PVC. There are around 120 winds of 20 gauge wire and start 2″ from the end. They are similar to the 80m coil for holes and hardware to attach wires.
I have the center up at 40ft and the legs hanging down to around 15ft.
You may have to tweak the lengths to fit the part of the band that you use the most. I have mine for the top of each band for voice.
