After making a batch of nice folded dipole elements on my diy jig, I needed to work out how to mount them and feed them with 50 Ohm coax. The feed point impedance should be 200 Ohms so I needed a 4:1 balun.
I’ve got a strange fascination with folded dipoles. Single or stacked and phased, I just can’t seem to shake the need to build one from my head. So toady I have made a simple jig to help bend up a batch of folded dipoles.
