Loop antennas are a favorite among hams. They are a simple design and offer more gain than a half wave dipole antenna. A full wavelength loop antenna can have as much as 2 db extra gain over a dipole when compared at a similar heigh
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. Small loops for higher frequencies can be mounted either horizontally or vertically. HF Loop antennas for the 10 through 20 meter bands are small enough that they can be easily suspended vertically with their broadside radiation pattern pointed in a specific direction. The total length of a full wave loop antenna is the same as the driven element for a cubical quad antenna….Read More
