WebRadiation Patterns. A full-size Delta Loop, fed in the bottom corner, is a good low angle radiator and is great for working DX. This antenna normally has about a 3 DB gain over a 1/2 wave center fed dipole. The Delta Loop is not only a great transmitting antenna but a low noise receiving antenna. The direction of fire is broadside to the antenna. WebSmall loop antennas are also called as magnetic loop antennas. These are less resonant. These are mostly used as receivers. These antennas are of the size of one-tenth of the wavelength. L = λ 10. Where, L is the length of the antenna. λ is the wavelength. The features of small loop antennas are −.
