Rogers, Ar
It ain't no turnstile.
It is only two one wavelength long elements per side.
Each element is fed in the middle of the one wavelength wire.
Each one wavelength wire is bent at 90° in the middle.
One of the one wavelength wires is connected in the middle to the coax center conductor.
One of the one wavelength wires is connected in the middle to the coax braid.
The 1:1 balun is at the feedpoint.

If the elements were half as long, it would be a turnstile antenna of some sort.

But half-wave long wires should give it a horrendously high feedpoint impedance.

I'm baffled.

Yea, using a 1 : 1 balun on those 1/2 wave legs was the first thing I thought was out of sorts..

VERTICAL PLOT, Notice both have very high swr, I did not try to solve for swr, simply used 11.05 meters as one full wave.X VERTICAL.jpg

Good job. As expected, “Z” is extremely high on full wave dipoles. As is SWR. The proof is in the pudding. Or the model, I guess I should say.

    Sorry to hear you troubles, he is famous around here for his scams.

    My first thought was the i.r.s. may be interested in a long term money making scam without proper taxes being paid..probably more than electronics involved.
  • @ Toll_Free:
    My first thought was why hasn't someone paid him a visit. I mean, his address is posted above.
  • @ beakster1715:
    Good news! I opened an appeal case after eBay sided with superhawkwss6. I also opened an IC3 case & sent that information to eBay. Within an hour they responded, reversed their decision and returned all of my money. Unfortunately, superhawkwss6 stole my CB radio and eBay will likely not suspend or close his account, but rather allow him to continue his criminal activity. I think I'll still file a report with our sheriff's dept (the sheriff is a friend of mine) though I know this type of crime isn't worth their time. This guy needs to be stopped and I'm certainly going to do my best to make that happen.
