Running two wires at each end of the house can turn this into a horizontal loop.
Also less interference is created to neighbour s tv etc from cw than ssb.
500 hz or narrower cw filter really takes away many noises compare to wider setting of ssb voice.
A couple of years ago i had written an article on the use of my rain gutter on my home as my hf antenna.
1 two loop heights 2 two house types and 3 several bands.
I had great time.
The best smartuners to use for a rain gutter antenna are the sg 230 sg 231 or the sg 237.

This hoa buster antenna defeats the rules imposed upon amateur ham radio operators by using existing metal gutters as an antenna and enables external tuners to achieve a near perfect match from 10 80 meters.
Below is a photo of a simple effective and entirely covert hf antenna.
