Today I have to move my two main antenna feeders which wind their way untidily through the house from the back of the house, where they enter the building, to my shack in a front bedroom. This means getting up into the small loft space to run the cables across and down. Some years ago I had a bent end fed antenna on 10m squeezed up there and it managed to get to South America on QRP SSB. A small ground plane for 10m (with a capacity top hat to shorten the vertical section) would probably perform quite effectively.
UPDATE: Job done. It took about 1 hour and everything is fine.
