It's called a hex-beam. It is basically a set of 2 bent dipoles on each of several HF bands. One of the dipoles is driven and the other is a parasitic element. The wires are held in tension by the bent radial frame and spaced so that the dipole lengths correspond to the necessary wavelengths on each band. Usually they are for the 20, 15 and 10 meter bands, but all sorts of other combinations (i.e. 17 and 12 meters) are possible. The lower frequency bands (i.e. longer wavelengths) aren't practical because the size gets too big.
