3mm nickel plated copper figure 8 style swages I have bought in for use with the TE-Kevflex wire.
I will be using these on all the kevlar antennas I make, and also supplying them with the antenna kits I will be making.
I have tried these using crimpers as per the photo, and also using a hammer and anvil, and I cannot get them to slide or let go in anyway.
Nickel plated copper.
5 grams each.
