For a good number of years I did allot of experimenting with 1/2 wave inverted L's and T's on 160 meters with no ground system and had very good results.
I published a web page about it at http://www.wcflunatall.com/nz4o9.htm One night on 160 meters with 100 watts on SSB I got a 10 over S9 report from a station in England from here in Florida. 73, Thomas F.
