Regarding indoor antenna's for HF, as you know that is tough. I have used both a slinky dipole stapled to a sheet rock wall (grad student life), and numerous attic antennas. As long as you don't have a metal roof, and you are stuck indoors, put a dipole in the attic, that is the simplest and cheapest effective thing. Also effective and compact are various loop antennas, which could be put near a window or in the attic.
