    With the balun and auto-tuner you have a great antenna system! 
However it may be the wrong length. I use the 88 foot flat-top which 
works just fine on 80 and 40 meters, and 30 and 20 meters as well. With 
135 feet of wire your antenna will not load up well on 40 and 20 meters. 
But it will work great on 80 meters.

    The flat-top length is not real important and it should not be 
resonant at the Ham bands. The 88 feet is nice because on 20 meters it 
is a double bazzoka and has gain off each side of the dipole.
