They're harder to stick in

They're harder to stick in your eye. Beyond that *supremely knowledgeable blink* I really can't help.

 

Sorry :/ Someone here will know more though :)

 

While we're waiting... *tap fingers* welcome to the café!

 

 

Please wait here. Further instructions could pile up at any time. Thank you.

For me the answer is no & no.

For me the answer is no & no. But .....

.... so you're after a current response from a changing magnetic flux ( in turn proportional to a loop's enclosed area en-face to the field ) ?

If so then that assumes a wave polarisation, and in turn a probable direction to source. What do you want to pick up with it ?

At a glance you'd want exceptionally low impedance and a really good current amplifier .....

Cheers, Mike.

Before this goes much father,

Before this goes much father, what band?  Compared to what kind of vertical?

I will say if you have the ability for a vertical dipole it will throw a better omni-directional signal.

I'm a ham, but I have absolutely no idea how to answer the question.
