[QUOTE="Grodsik, post: 606603, member: 322153"] A half lens on top of a metal plane has the same multisat capability as the full sphere. I'm thinking of building one out of polypropylen (PP), DC = 2.3, and loss tangent = very, very low at most frequencies. Any experiences? The actual material I'm considering is cheap PP rope, and either tie the rope in a large ball, or cut the rope in short pieces (fibres) and fill a half sphere container with it. Since the size of the fibres is much smaller than the wavelengts one can use the packing density of the fibres to control and lower the DC value by 20-30%.... Any thoughts if this is viable? Thanks for a good thread! [/QUOTE]
