Being a tower rookie, I learned this lesson the hard way, needing to replace a rotor and no lower bearing. Necessity being the mother of invention, it turns out that for a 25G tower and a 2" mast, yo

If I recall, the Mosley beams faired quite poorly in the K7LXC/N0AX test. These beams do have a reputation for being well made, however. The best performing were the Force12. The Optibeam and the For

You can stack them, but the interaction defeats the purpose of having monobanders. I just ran through a modeling cycle with my stack and the 15m especially gets whacked. The hex beam or a single trib

Cut the element as a DE and use a relay switched coil in the center. I'm not sure how that works in the trees but that design does work as a DE/REF + DIR/DE combo when the dimensions are stable. 73/j
