Look, no antenna
If you are frustrated by the inability to put up as good an antenna as you would like, take a look at the experiments being conducted by Roger, G3XBM, using an antenna made in the ground using 20m spaced earth electrodes. The results are quite amazing.
Unfortunately many of us in the UK cursed with antenna restrictions also have postage stamp sized plots where achieving 20m separation would involve having one electrode in next-door-but-one’s garden. But if your only problem is awkward neighbours, not the size of your plot, this might be something to try.
