<br>
<b><u>Change history:</u></b><br>
<b>[23-Apr-23] - V9</b> <br>
* Changed the frequency list to include VHF (2m) and UHF (70cm) bands.<br>
* Reduced minimum loop diameter to 4 cm.<br>
<b>[12-Feb-22] - V8</b> <br>
* Changed the frequency list to include top and bottom frequencies of each band. This is to highlight the range of capacitance required between the top and bottom of each band.<br>
* Increased max c/a ratio from 10 to 30.<br>
