Uh, did the antenna work? Not a RF guy but as far as i know, the dimensions of the "wire" matter.
And btw, cheap chinese plastic things are likely to leak some hazardous chemicals.
It "works" but isnt perfect. The length matters, but it does work and is the right(ish) length. I don't have the instruments to test it properly.
More, it just isnt very practical because it doesnt work much better than a small whip antenna. I do have a more powerful radio I need to test it on eventually, but it uses the wrong connector for that and I have to buy an adapter
The aim with simple antennas is to get their length right to match the radio waves. Often at 1/4 of the wavelength.
The type of metal an antenna is made of matters, as the speed of light is different in different materials.
I suspect if it doesn't work well it's because the manufacturer either made it the wrong length or used a fibreglass tape measure rather than a steel one
