<b><u>Notes:</u></b><br>
|

The Magloop Antenna Calculator was developed to predict the characteritics of a small-loop (aka "magloop")
|
||||
antenna, given physical dimensions entered via slider widgets. It assumes the main loop is made from a round
|
||||
copper conductor. There are many magloop calculators available
|
||||
online. Some require installing a program on your computer, which is OS dependent. Some others are browser-based,

copper or aluminium conductor. There are many magloop calculators available online. Some require installing
|
||||
a program on your computer, which is OS dependent. Some others are browser-based,
|
||||
but require parameters to be input using a keyboard. I wanted to create a tool that took advantage of the
|
||||
touch-screens and high-speed of modern mobile phones, to allow users to get realtime feedback of the predicted
|
||||
behaviour of a magloop antenna. This would help a radio amateur to decide on the characteristics for the build.<br><br>
