- Dual Band Wire Beam 12 and 17 m
- The Dual-Band Wire Beam was inspired by L.B. Cebik's (W4RNL) article The Elusive Moxon Nest. Fiberglass tubing spreaders, Flexweave elements, an aluminum hub, and two die-cast aluminum flanges combine to provide a 12/17m Moxon nest with one 50 ohm feed.

- The Moxon Rectangle on 2 Meters
- We often think of the Moxon rectangle as strictly an HF antenna. However, its small size and special far field pattern lend themselves to some VHF applications. So let's see how to adapt the design to 2 meters (as a popular band choice) and also see a few of the uses to which we may effectively put the design.

- Cebik Moxon Rectangles
- The Moxon Rectangle is growing in popularity as a compact 2-element array that approaches a full-size 2-element in gain but with a far superior front-to-back ratio and a direct match for the standard 50-Ohm coaxial cable.
