Hi

Yesterday i made some test with mini zahori and it can detect my home electrical power lines on the wall about 8 to 15 centimeters away from the wall.
The sound comming from the buzzer of course is current but not a beep.
I also tested the unit in front of my old TV set and it detect current from just about 30 or 40 centimeters, no more than that.
My questions now are:

1.- Modifing my antenna could get more sensitive?
The distance fom L1 to L2 is important and if so what is the correct disctande. Mine has a distance of 0,5 cms?

2.- MY antenna wire is 1.6 mm in diameter, what is the best wire gauge that probes to work better?

3.- The first time i build mini zahori i placed 2N3819 reversed and seems to work to, but now i conecter the rigth way. So i whant to know if this could burn my 2N3819? This is important to know, cause this may cause my detector to work poorly.?

I hope someone with more knolegments and expirence can help, cause i m realy enthusiastic about this experiments.

Thanks and best regards
Nelson
