Loop Antennas
According to Dr. David Jefferies
“A Loop antenna has a continuous conducting path leading from one conductor of a two-wire transmission line to the other conductor. You may think of it as a “coil that radiates”. The coil may have only a single turn.”
Loop antennas are very popular among low band enthusiasts, since allow operations on full wave antennas in a limited space, when compared to dipoles or beverage antennas.
Here a selection of 7 interesting Loop Antenna projects, that includes skywave horizontal loops, square and triangular loops aerials
The multi band HF loop antenna, a good performer on 80 and 40-10 meters. This excellent article covers all aspects of designing a resonant loop antenna, examining gain and radiation patterns, and describing practical notes on how to build this antenna.
A Wire resonant loop antenna for 160 meters band article by N4KC
A rotatable hanging loop antenna that has been specifically designed for hanging in a tree. Horizontally polarized with a broad azimuth pattern and gain of nearly 3dB over a simple horizontal dipole!

The antenna is a 10 - 160 meter horizontal loop fed with 450 ohm ladder line all the way into the ham shack to an Palstar AT1500BAL balanced line antenna tuner
