Mini antenna from Amazon?

[Gadgeteer2000]

Hello all,

found this "antenna" on Amazon: https://www.amazon.ca/dp/B08FCMT2JH...olid=1NVB224PDC8LI&psc=1&ref_=lv_ov_lig_dp_it

Would you be so kind to have a look and tell me
- is this really an antenna?
- does it work (when placed indoors)?

Thank you for any input.

It's probably a copy of PA0RDT Mini Whip Antenna design. Do a search for that. There are several articles and web sites about it.

Something that small is going to be crap below 30mhz. Physics is unforgiving.

Thank you! Will do. Amazing - so this is really an antenna! I am learning new things every day.
Now time to read up.
Thank you again!

It looks like it might be a Chinese ripoff ...

it can be made to work - after all, the well known University of Twente SDR uses a PA0RDT antenna. However they do take some work to tame them. See this article from SWLing.com

Yes, I have one of those. They have to be installed per directions but in that, they do work well.
Indoors you might be a bit disappointed.
I have an 18 foot length of copper wire strung out the window, goes to an antenna tuner then to a preselector.
Works about the same as the mini whip just above the roof line.
Another hint is use good low loss coax coax. Don't skimp there.
This is the mini whip I got,,the kit, but they have assembled also. Not the cheap Chinese knock off.
