Well, yes and no ! 
No, so long it is isolated on a tree. Quater wave must be grounded with at
least one quaterwave elevated radial or with good counterponce. It works
when it is half wave insulated.
I had four of half wave in 4 directions sloping down from the middle tower
then at the point about 3 meters above ground bent back to  center tower. I
tune them as director and reflector switched with vaccuum relays. Great

opinion..John K1GUN

Well - yes - it can help.  You can probably get a bit of gain - but maybe 
more importantly - get some front/back.  

One limitation is that you will only get it over a pretty narrow frequency 
range (30 kHz or so).
