&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;A loop antenna in the horizontal plane. Typically at least 1 wavelength in circumference, for receiving purposes any size will work, the larger the better. Due to the high impedances involved, the antenna is often fed with a [[balun]], such as 9:1, 12:1 or even 16:1.  It could also be fed with balanced line, such as twin lead. &lt;br /&gt;
&lt;br /&gt;
Being a loop antenna, the noise pickup is generally much lower than other [[antennas]] such as the [[dipole]]. &lt;br /&gt;
