Oddly enough, the full sized one I have, in addition to OK performance
on 80/75, 40 and 20 works better than anything else I've tried on 17.
It really does do poorly on 30,15,12 and 10 though. Go figure...


At the higher frequencies, small variations in design and environment
can cause large shifts in characteristics due to the shorter wavelengths
involved. For instance, if the dipole is a little longer than 102 ft,
the series-section transformer is a little longer than 30 ft with a
relatively low VF, the G5RV antenna system's resonant point will shift
a lot on the higher bands. Also, installing the G5RV in an inverted-V
configuration can change things considerably on the higher bands. I'm
glad it works well for you on 17m. That's a neat band.
