<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. There are many magloop calculators available
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
behaviour of a magloop antenna. This would help a radio amateur to decide on the characteristics for the build.<br>

<u>Inputs via the slider widgets:</u>
<ul>
<li>&#8960a : Copper conductor diameter in millimeters (mm). Estimated equivalent AWG wire size is also displayed where appropriate.</li>
<li>&#8960a : Copper conductor diameter in millimeters (mm).</li>
<li>&#8960b : Loop diameter in meters (m).</li>
<li>N : Number of turns or loops.</li>
<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)
<li>c/a : is the spacing ratio; based on 'c' being the inter-winding spacing for multi-turn loops measured between conductor centers, and 'a' is the conductor diameter. (Must be >= 1.1)
A low-value will increase the resistance due to the proximity effect.</li>
<li>Tx : The transmit power. This affects the predicted voltage across the capacitor.</li>
