My new portable 6m Moxon. Assembled in the basement Saturday morning and tested on the deck prior to the June VHF contest.
- Spreaders - 4 Fiberglass driveway markers (48”)
- 16 gauge wire - 20’ or so
- Two pieces of 1/2” copper pipe for hub- flattened in center, ends bent out 20 deg from centerline.
- U-bolt - attaches two copper pipe pieces back to back and holds antenna to mast
- Gap Spacers - Two pieces roughly 4.5” each, wire zip tied along top
- Paracord - four small loops to thread wire through, zip tied to ends of spreaders
- Zip ties - many, as needed
- Coax - RG8X
Aside from the coax, mast and hub, entire antenna collapses down into about 2” x 48”. Hub is about 12” x 5” x 1/2”.

The G5RV Myth →
No one can deny that the various commercial G5RV antennas are a story of marketing and sales success. But from a performance standpoint - no so much. The article link takes you to a discussion of what the G5RV is and isn’t. Without a great tuner, the emperor has no clothes. But, with some adjustment in radiator and feedline length and feedline impedance, another derivative (see the last paragraph) gets fairly close to the mythical ‘all-band antenna’.
