A loop antenna is a radio antenna consisting of a loop or coil of wire, tubing, or other electrical conductor usually fed by a balanced source or feeding a balanced load. Within this physical description there are two distinct antenna types: The large self-resonant loop antenna has a circumference close...
The Delta antenna is a variation of a loop antenna. This type of antenna is well established in the SW bands, and, in practice, they are very effective at УSW. Connect the power cable with wave resistance of 75 or 50 Ohms is via g-matching device.
The effective position of the Delta loop should be on a half wave length high above reflecting services, on that point in the antenna where the radiation pont is half a wave (dotted lines in picture 5) For DXing you can best chose the two vertical forms out of picture 5 namely the B type, with a radiation angle of 27 o and the E type with a ...
Nov 01, 2015 · A loop antenna is usually one full wavelength long but some loop antennas are quite large and may be several wavelengths long. Larger HF loops, such as for use on the 80 or 160 meter bands, are usually mounted horizontally and are often used with an antenna tuner on higher frequencies.
