1. Basic Design Approach

We'll calculate the L and C values for an L-match network, which is a simple and effective matching network. We can make the following assumptions:

The transmitter has a given source impedance (usually 50Ω).

The antenna has a load impedance (Z) that may differ from 50Ω.

2. Form Inputs for User Data

The user will input:

Source Impedance (Zs): The impedance of the transmitter (usually fixed at 50Ω).

Load Impedance (Zl): The impedance of the antenna.

Frequency (f): The operating frequency of the AM station (in kHz).

The tool will output the values for:

Series Inductor (L) or Capacitor (C)

Parallel Capacitor (C) or Inductor (L)
