<li>Tx : The transmit power in Watts. This affects the predicted voltage across the capacitor (Vcap), and the RMS loop current (Ia).</li>
<li>Re : Additional resistance due to external losses, due mainly from capacitor contact resistance and proximity-to-ground effects. Use Re=0.0 to assume the loop is in free-space.
Adding Re will reduce antenna efficiency, Q, Vcap and Ia, while increasing BW.
In a study [1], a 1 m diameter loop of 22 mm copper tubing at a height of 1.5 m above the ground at 7 MHz had a calculated capacitor contact resistance of ~190m&#937;
According to [1] and [2], a 1 m diameter loop of 22 mm copper tubing at a height of 1.5 m above the ground at 7 MHz had a calculated capacitor contact resistance of ~190m&#937;
and an additional ground proximity loss resistance of ~30m&#937;. Note that ground effects are height-above-ground and frequency-dependent.</li>

<li>Cu or Al : selects the type of metal conductor (annealed copper or aluminum).</li>
