This has worked for me. I don't have a big signal, but 
it works well enough that what I can work is limited as 
much by receive noise as by my transmitted signal. In my 
case, I don't have a "good ground," but I do have a 
reasonable counterpoise.  It loads pretty easily with a 
TenTec tuner (and no external capacitance). In fact, it 
works better than the same antenna loaded as a dipole on 
80 in directions that are off the end of the antenna.

which is from Kraus. 

It is QUITE important that there be no choke balun in 
the usual place at the dipole center. The first time I 
tried this configuration, I burned up a conventional 
balun with 100 watts during the first contest weekend 
that I used it. The reasons should be obvious.
