Hi Franco I used your type of antenna in my LRL became more sensitive and even the distance increases by 30%
but I ultisé another thing. I introduced in the coil in the plastic tube a normal antenna (see photo). it has become more sensitive, and thus increases the distance

Thank you for this idea. and I try to test your new LRL

So I want the schema to ten LEDs with the circuit LM3914
question after you if the voltage detection increases the LEDs light as a VU meter?
and if necessary to add an audible alarm (audio) if the target is detected further vusiel signal (LED).
