"Why antenna balun? because this balun is an integral part of the antenna. So what is it? It behaves in the same way as a Pawsey stub. However, there is no velocity factor to take into account or calculate. You simple cut a 1/4 wave length piece of rod, tube or wire. Connect one end at the feed point (inner core) and the other further along the boom making sure it stands clear of the other elements. That's it! It really is that simple." |
