This kit is an alternative to the pre-assembled 20/40 Wire Element Set. There are dozens of possible band combinations in a linked dipole antenna. This kit allows you to build your own custom wire antenna elements for any combination of bands using the same hardware we use in our pre-assembled elements. You decide what bands you want to operate, cut the wire, attach the strain relief hardware and solder on the banana connectors. The kit includes 100' of high quality antenna wire with one end finished off with a strain relief loop crimped in place, plus a male mini-banana plug and S-clip.
