The PackTenna Mini Linked Dipole has a high quality balun that matches the unbalanced feedline to the balanced antenna. The antenna includes two 20m quarter wave wire elements. The wire elements plug into the feed point with gold plated mini banana plugs. The ends of the wire elements are finished with female banana sockets to allow you to plug in additional wire elements using an S clip to take the strain while the banana connectors tangle below the clip. Using high quality PTFE (Teflon) coax, the balun reduces common mode current from flowing back down your feed line and causing RFI problems. The side loops on the balun PCB provide mechanical connection points for the wire element S-Clips. The balun feed point PCB is secured to the antenna mast with two mini-bungee cords. These bungees grip the mast tightly without crushing it.
