Lightweight beam antennas: Moxon vs Spiderbeam

The 2013 solar maximum is almost here, the 10 meter band will be booming soon and you cannot let it go by without using a decent antenna; it would be a shame, considering how cheap it is to build yourself a decent performing beam in this band.Today I am looking at two of the most efficient designs that a homebrewer can use for such an antenna: the 3 element Moxon and the Spiderbeam; both are variations of the 3 element Yagi and require just a mast, 4 fiberglass fishing rods and some wires to get going.  Of course, this will mean that both will offer a visible performance increase over a vertical, but either of them will be lightweight enough to use in portable operations or at home, requiring a much cheaper rotator and having less footprint than a solid full Yagi. Lightweight 10m band antennas: 3el Moxon and Spiderbeam The images speak for themselves as how these two antennas are supposed to look like and I won’t go into details about their history or building instructions, there is alot of that around the internet already. What i’m interested in is their performance, so I ran a few simulations with EZNEC; the settings are these: –  15 meters above medium ground (0.005 / 13)– 1mm copper wire with 0.3mm PVC insulation–  tuned for optimal SWR from 28 to 28.5MHz...
