The schematic you find here comes from another site on the internet, but because it's on so many sites, we don't know who actually designed it. However it's a nice one. Capacitors: C1,C4 22pF cer. C2,C3 51pF cer. Coils: L1,L2,L3 #18 bus wire, 1/4 diameter, 3 turns * Form the leads from the capacitors as shown in the little figure below. Then solder them from the pad to the outside ground area. * Be sure that the turns from the coil are seperated by the same distance as the diameter of the wire * Form the leads from the coils as shown in the little figure below. Then solder them in place. * Place the filter in a metal box, with rf-connectors on both ends ( SO239(=PL259), BNC or N-connectors)
