Default apartment antennas and rfi

Those of you who are using apartment antenna I would love to know of
your experience.

I had a nice cw qso with a fellow in an apartment using a 9:1 unun made by
balundesigns.com to a straight wire off his apartment balcony to a tree.
Such a wire could be made very small and almost invisible, if that is a
possiblity. Also, easy enough to homebrew your own 9:1 balun for such, if
you are inclined.

If you could feed with parallel line, an end-fed zepp might work well, but
would require an end support, such as a tree, and the parallel is more
visible.

If the second support is not practical, many have used coil loaded verticals
off a patio. This could be done with a collapsing fiber glass pole for
removal when not in use.

Both schemes would require a tuner.
