Re: At what frequency(ish) does a small receiving loop lose directivity?


Chris Moulding
 

Looking at your example of a 1.2m loop it will have a full wave resonance like a quad loop at 79.6 MHz.

On that frequency the maximum gain will be broadside to the loop..

At low frequencies where the loop is a small fraction of a wavelength the sharp nulls are broadside to the loop.

You will probably see the loop lose it's directivity as it changes from one mode of operation to the other around 25 - 30 MHz..
