Even with the end fed half wave wire you still need a ground as you have no coax to
provide the counterpoise. A length of wire [maybe 20ft] laying stretched out on the
ground should do. That would be connected to the the QCX RF ground point.
Some will say the wire needs to be a quarter wave but wires are seriously detuned
laying on the ground.
The antenna element still needs to be a half wave or the SWR will be high and the
finals maybe history.
FYI I use the PAR EF-40/20/10 I've had for over 15 years and its my go-to portable
antenna. Replacing the wire on that one with one cut for 17 and 15M makes for a
light kit and most bands I'd do portable. That plus lengths of 1/8" dacron cord,
and 20ft of coax I"m set anywhere there are trees.
