For what its worth Id stick with the dipoles at that height. I tried 1,2 and 3
wave length loops at ~110 ft
(vs dipole at 110 ft) and "on the average" the dipole worked the best. This
is completely unscientific but
two years of playing on 160 the 1 wave length loop was quieter but didnt have
the coverage of the
dipole, 2 wave length was the worst (noisier that the one wave length and didnt
hear as well) the 3 wave length was only up a short time due to a snow
storm but it didnt seem to perform any better than the 1 wave length.
If I remember correctly odd wave length loops tend to model better than even
wavelength loops.??

I have been contemplating a sky loop
to replace my coax 160/80M fan
dipole. The loop would be fed with ladder line so I could
use it on 160-40M.
It would take a bit more effort clearing an area to get up
2wl of wire
but it could be done. Is the effort worth it over a 1wl
loop? An
additional issue is I can only get it up about 50'.
Right now the dipole is at 25' and works very well with the
hams I daily
keep in touch with in the 500-600 mile range, but is limited
in it's
bandwidth.
