​Over the years I have built many accessories for my stations. Here are the most recent.

I decided to build a 10 Meter Moxon to install at my QTH. I found several articles pertaining to the construction and settled on the design by L.B.Cebik from 1997. Following are details on the build along with the components needed. Most are available from DX Engineering, Amazon, Home Depot and Lowes.

The Moxon is taking shape!
I have decided to add two elements for 6 meters using the open sleeve feed method. I saw this being used on the Momobeam DUO4 6-10 antenna that is available from the ARRL. Dimensions of the added elements and spacing requirements shown above.

Click the 3 pics below for a closer look at the construction techniques and materials used.
