A Cobweb sounds the ideal answer to my problem of working HF at home, where I can't really have an antenna up. Currently I am using a wire dipole for 20m that I put up after dark on a telescopic fishing pole. I'd planned to build a 20, 30, and 40m trapped inverted V dipole which I can just squeeze in using a 10m fishing pole. As I understand it, each trap will add loss (I was planning on tuning in band for simplicity which is worst loss case scenario) and also narrow the bandwidth of the following dipole(s). However the Cobweb sounds good, in particular I like the @G3TXQ design. I was wondering if it would still work the same if I built it to look like the rotary washing line already installed in my garden (pic attached) rather than the usual flat construction. I could have that low by day and sneak it up at night. Just to be clear, I am thinking of a fresh build made to resemble a washing line, not using a washing line as the basis of a build. typical washing line like I already have in my garden, with upswept 'spreaders'.
