Short answer, yes, as long as you keep the spacing. Long answer, I'll never know why the J-pole got so popular. It has no gain and is only slightly better than a rubber whip.

I have made a few J pole antennas, and they worked way way better than a rubber duck antenna, and work quite a bit better than any dipole I have had, I never knew they were not suppose to have gain.
I made them for 2M and 440, never tried one for 6M or HF

Actually a JPole has Gain when compared to an Isotropic Radiator.....  The reason they became popular is that they are VERY EASY to build, and tune to resonance, without any special tools or instruments. Any Yahoo can make one work...  Just Say'en.....

that and also that is very tempting having a better than a whip antenna in your coat pocket (well....almost)
