John, in Post #52, Mike (Crackle) claims to have covered the whole house simply by connecting his Minimod to the central heating pipes!
A lot simpler than what I was going to suggest - a wire running the length or width of the house, whichever is more convenient, at ground floor ceiling level (or floor level on the first floor).
It can be surprising how far a little power from a low power transmitter can go.
I built a one transistor VHF modulator in the 60s that covered our long workshop at the back of the building, where it was located but also gave excellent coverage of the shop downstairs at the front of the building.
The aerial? None! It relied entirely on radiation from the one coil and, unlike previous attempts, this one was so stable that it could just lie on the bench. It took a finger closer than half an inch from the coil to de-tune it!
