I built the "cloths hanger" antennae, but used 14 gauge wire twisted and a slightly different spacing than some (based on engineering information). Placed outside, and attached directly to the TV (no splitters, no preamp), I was getting 70 - 100% signal strength on the three OTA digital channels (CTV, Global and CityTV). Cost to build was basically $0 as I had everything laying around already. I placed the antennae in the attic and it now goes through a 3 way splitter...
