point at which it is fed) the 1- λ loop will show a small gain over a 1/2-λ dipole. Theoretically, this gain is about 2 dB, and measurements have confirmed that it is of this order. The 1-λ loop is more frequently used as an element of a directive antenna array (the quad and

Direction Finding Antennas
www.qrz.rurather than at the bottom, will not alter the polarization and will only degrade performance. To obtain horizontal polarization from a small loop, it must be oriented in a horizontal plane, parallel to the earth. In this position the loop response is essentially omnidirectional. The earliest loop antennas were of the “frame antenna” variety.
