Constructing loop antennas
http://www.webclass.org/k5ijb/antennas/Small-magnetic-loops.htm There are a few basic construction methods for wire loop antennas: 1. stiff wire (mostly self supporting) 2. strung wire (on a framework of some sort) 3. hung from trees, masts, or other supports None of these need to be particularly difficult to build, although multi-element versions at HF can be … See more Solid wire in the 1.5mm to 4mm (AWG #6 to AWG #14) range is often stiff enough to be used with minimal supports at VHF / UHF. Figure 1 shows a cubical quad for 2m, where a single … See more These use a rigid framework that supports all parts of the wire, and can use a thinner or more flexible wire for the element. This is the common construction method for rotatable quad … See more Wire loops for the lower bands are often strung from trees or masts, either in the vertical plane or horizontally. The article on Building a Simple Wire Dipolediscusses many common approaches that can be used, and this … See more
