Portable delta loop feedpoint/insulator & balun.  Balun is in the pink container.  Coax will attach where red & green wires are on front bottom, and feed through the balun which is plugged in on the backside, and then to the antenna wire (green) which is fed through some of the mounting holes on the sides for strain relief.

The arrangement should provide flexibility to allow other wire antenna types and baluns (2:1, 4:1, etc.) to be used. The other mounting holes will be used for support cord.  Apex of the delta loop and other corner will be set/hung by large clothing buttons.

Perhaps an expensive approach if you had to purchase the binding-post wall plate, but I was given a bagful by a fellow ham, so the price (for me) was right.

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’.

So, how am I doing?

Longtime Mayor of NYC Ed Koch used to ask that of the public/media all the time during his tenure.  At the start of the year, I made a 'To Do List' regarding things I wanted to accomplish in amateur radio this year.  We’re at the halfway point of 2012, so let’s see how I’m doing….

  • Ditch the paper log for a digital one <Yup>
  • More portable/outdoor operation <Easily surpassed last year’s efforts>
  • Organize my (corner of the basement) shack <May never happen>
  • Get comfortable with & operate more digital modes <In Process>
  • Build & experiment with more antenna designs <2m Moxon done, Sat ANT in process, 10,15,20m top-loaded vertical 50% done, 6m moxon later>
  • First SOTA activation <Activated one of the few unactivated peaks in NJ>
  • First Satellite Contact <Building Homebrew Diplexer & Arrow ANT now>

So, all in all, I’m pretty happy with my progress, with half a year left.
