I use one as a portable antenna, and I never use a ground. Most of the
time it works pretty well, but it does pick up a lot of noise.

Anyone using the PAR Electronics EF-SWL Antenna please advise if a
ground is necessary. Will using the PAR without a ground be any better
than a 50' random wire? I live on the second floor of a condo and only
can use a very thin hidden wire from my receiver to a nearby tree. No
ground available. I read all of the glowing reviews of the PAR but all
of them are using a ground. Unfortunately I don't have that luxury. Any
other recommendations appreciated.
Thanks...Bob
