             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,
             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

-                <li>c/a : 'c' is the inter-winding spacing for multi-turn loops measured between conductor centers, and 'a' is the conductor diameter, so 'c/a' is the spacing ratio. (Must be >= 1.1)

                     A low-value will increase the resistance due to the proximity effect.</li>
