looks like a 1/8 wave 2 meter design.

the end points look like they are well suspended, But I'm not certain how clean the signal is to the feed point.
your thoughts??

that's not a dipole,
it looks more like a slot antenna made from wet string, they usually have a cavity filter at the feedpoint.

Slot antenna's are usually fed with microstrip feedline.

Signals will be in and out at the feed point.

Resonance of antenna will also be checked as near feed point as possible.

your thoughts??
we need more pichers camera man went to sleep after one shot
you call yourselves antenna gurus need shots of the frontal lobes and 2 main directors to properly analyze the pattern produced by this antenna design it does however give a new meaning to standing wave ratio feedpointimpedance and skin effect

Definately a BASE LOADED antenna. Very low take off angle.

I think the SWR would be dependant on the angle of your dangle.

VSWR would depend on the angle of the received input!!

This new dipole antenna may just be a great receive antenna or just another dummy load per say.

I had one of those one time. They become pretty broadbanded after time. They cause a lot of static, and can be a bitch to put up with.

I had two of those over the years. Both where high strung and didn't receive worth a Dam. I gave one to a neighbor and a stranger stole the other one + all my gear and the shack. I 'm still laughin at his stupidity he got a real mud duck in a drafty shack with bad plumbing.
