Inductance as a straight wire over the plain with one grounded end:
Inductance is used on UHF. Of course, we have to present this inductor as a segment of the transmission line to get the more right result. However, this formula has a reasonable accuracy.
The calculation formula is taken from the ARRL Handbook For Radio Communications:
- L = Inductance µH
- a = radius of the wire in inches
- b = length of the conductor parallel to the plain in inches
- h = height above the plain in inches
Proposed below calculator uses this formula with sizes transformed in the metric system:
ENTER THE INPUT DATA:
| b | = | – The length of the conductor |
| h | = mm | – The height of the conductor |
| d | = mm | – The diameter of the wire |
RESULT:
| L | = | – Inductance |

Only on K7MEM's site calculation follows the same formula, but has an error: calculator uses wire diameter instead of radius.
