If you give us more info on your PRIMARY band(s) and mode of operation, we could give you some good ideas since many of us have over 60 years of ham experience, often from many states and countries. For example if your MAIN interest is 75 meter local or regional SSB nets, where RX signals are often strong, one type of advice is relevant. If you want to work some DX on 20 meter CW other approaches may be appropriate.
For example, when I operated portable CW from my daughter's house in urban area of California, the noise made operation impossible with any antenna near her house. I laid a wire dipole on her back yard wooden fence cut for 40 meters, average height around 4 feet. I think I shortened one or both legs a bit with loading coils, and/or zig-zags. (it was a few decades ago). It was a very good quiet rx antenna which was at least 20 or 30 feet away from any houses. Had many very nice QSO's out to a few hundred miles with 2 watts of CW. As a tx antenna it was not great (RST 549, etc.) but had some long rag chews. Now this was probably back when propagation supported this type of operation. If I had to operate from that location for an extended period, I would put up a separate TX antenna, even near a house, which might even work for some DX. This idea may work for CW or digital operation, but SSB or AM may not.
One idea is to build a simple (wire ?) antenna for a single band and see how it goes before you spend money and time. For DX 20 or 17 meters might be a start. For shorter range 40 or 80 may be useful. You will gain very useful information for designing your ultimate antenna. Think outside the box. A wild example, when I operate portable from various states and Europe, usually I just hike up a trail, or city park, or whatever. It is fun, usually rx noise is low, but when I operated from northern Norway, or even England it the winter, it was a bit rough, but still fun in my warped mind, but I am still young at 81 years old.
