I have a 63 ft. end-fed wire antenna which I am using with an MFJ-949
versa tuner, and 4 counterpoises cut for 1/4 wave on 15,20, 30 and 40
meters. Far end not very high, about 25 feet up a tree, shot up there
with a slingshot. Pretty thick foliage right now, but not a lot of the
wire is showing and in the clear as the near end of the wire slopes
down almost to ground level (townhome QTH).

Bit of an underperformer, and I was wondering whether it would be
worth my while to install a ground rod in order to ground the tuner,
and whether that might improve matters a bit,

Thanks for any information.
