Topband: 160, 80 and 40 Meter Inverted L Tuning

[Bill Smith]

I put up a 160-meter Inverted L in my backyard with traps for 80 and 40 meters.  The vertical section is up about 35 feet with 31 feet of wire between the 80-meter and 40-meter trap.  From the 80-meter trap to the end of the antenna is 60 feet of wire.  It is hung as a sloping U.  At the end of the U bend in the wire is a 4-inch pulley.  It's the best I can do with my small yard.  I have tried various lengths of a counterpoise as well as my radial field with no luck.

I obviously have a lot of research yet to do but wanted to see if these results make sense or not.  Any ideas on the best way to tune this?
