No. 26 magnet wire is invisible and works good as an antenna. If there are convenient trees around, that, a ground (and a cold water pipe will do nicely in a pinch) and a tuner will do just fine.
Attic dipoles are also good for the bands you can fit. I'd say use a balanced doublet with a matchbox.
And, if all else fails, a mobile antenna on the car with feedline run into the house can ALWAYS be done, as in, hide it in plain sight!
Done all three of those and worked my share of DX & stateside rag chews & contests with fun results.
