“Nearly two years ago, we decided that we needed a better antenna for all band operation to replace our traditional use of wire dipoles. Unfortunatly we do not have the option of putting up many towers with a large quantity of yagi’s so the antenna had to be visually low impact, cheap, all band and allow us to be competative in contests.
Callum M0MCX and James 2E0YOM began researching various options but nothing appeared to fit the bill. The basic 1 wavelength loop was the obvious starting point as this provided the potential for all band operation.
After many hours of research, modelling and experimentation we discovered that the use of horizontal triangular loops would provide us with the antenna we needed. Traditionally this shape of loop is used in the “Delta Loop” configuration and is widely believed to be a good NVIS antenna when mounted horizontally and a DX antenna when mounted vertically. We discovered that this is not always the case, when the loop is small <=1 w/l and low to the ground it behaves as you would expect and is a reasonable NVIS antenna, one you start getting to sizes of >=2 w/l at over 1/4 w/l above ground then the loop starts to exhibit some very high gain at low angles.”
