Multiple passive loop antenna question

T

tvnut

The question is simple. The answer may not be.

If one passive loop antenna, such as the Tecsun AN-200, helps reception, would two help even more, as is the case with, for instance, stacked bow-tie antennae for UHF? Would the mathematical formula be the same? (I'm presuming there would be at least a bit of help.)

I've found only one article on the net about this, and it concentrates on using one loop as the booster for the desired signal and the second to degrade an adjacent signal. It says nothing about getting extra oomph (technical term) from the desired signal.

We've got some technical sharpies hanging about here. Gentlemen, what say ye?
 
Just experimenting with two of them, I think sometimes you can enhance nulls, and I've heard of guys off-tuning one a little to try to null a station or direction while the other loop is enhancing the reception in another direction, but I've never worked with it enough to know for sure. Best thing probably is to experiment.
 
Yes you can

This is the antenna i use:

A tunable loop and i can use one for "reception" and one for "nulling" if i so choose, but it takes some fine tuning and placement.
