Topband: parasitic element

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

my existing 135 quarter wave vertical to give me a little more gain to the
NW my question would it work?the the quarter wave wire would be insulated
from the top of the tower and sloping toward the NW and another insulator at
the far sloping end and anchored to a tree...appreciate anyone's
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).
