As the name suggests, it is simply a dipole with the tips folded towards each other. In this case, a full-wave dipole. The span of a standard folded dipole is aprox 0,5 lambda
A collection of antenna projects by W4RNL L.B. Cebik collected in a single link page by ON5AU. Includes ARRL QST, Modeling and Understanding Small Beams and books
Article based on ROHN engineering specification that will guide on proper guying heights and guy lengths when guying ham radio antenna masts. It will help you determine ahead of time the proper length of guy wires and the distance from the base of the mast to the anchor points
A page describing how to home made a custom 9:1 balun for a common portable wire antenna. The author suggest to use 4C65 or FT140-61 toroids instead of the common Amidon T200-2
