Increasing the number of turns increases signal VOLTAGE
but also increases inductance. If the radio electronics
are resonating out the inductance, you don't want to mess
with the value of inductance. (If the radio electronics
are NOT resonating out the inductance, no wonder you have
such poor sensitivity). If you double the diameter, but
use 70.7% as many turns the inductance will remain the
same. You can also make the loop taller but not wider.
This will still give you more pickup area but will not
exceed the space behind the radio.

Shoul! dn't just using more turns on the stock form intercept more
signal and improve the SNR? And how about more turns AND also changing
to a larger antenna form to wind turns on? Since it's a shelf stereo,
I'm size limited on space for spinning the antenna around to the best
reception.
