I used three different inductance calculator. Result makes me irritated!
Details was:
diameter= 4mm (2mm radius)
High/length= 7mm
Turns= 8
1st calculator: I used a calculator by sm0vpo (harry lythall's) and got 119.27nH.
2nd calculator: I used a small software program and got 162.8nH.
3rd calculator: I used a calculator based on web page and got 114.53nH.
The 3rd calculator is based on this formula N^2 x r^2 / 9r+10H and I did by hand and got same as 3rd calculator.
But among 3 calculator values are different. 2nd is VERY different! I learnt: 'nH' on RF impedance matching network is VERY critical for desired output. If I used these confused values may be I will be hell
Review once and suggest me please for best!
