On a thread here the recommendation was made to use an end-fed wire antenna as a simple HF solution. https://ultimax-antennas.com/store/p10/ULTIMAX_HW-END_FED_(NO_TUNER_ANTENNA).html In my home, I imagine I could set up a HF transceiver in the office, and run a coax through the wall up into the attic. There, at the peak of the roof inside the attic, I have a gable vent panel where I could mount the end-fed hardware. From that high point, estimated to be at least 33 feet from ground level, I think I could string the antenna wire parallel to the roof truss, below the shingles and plywood decking, inside the attic, then out the roof at the soffit ventilation gap below the aluminum gutter at 90 degrees to the gutter. From that two-story point, the antenna wire would continue downward along the roof line angle (7/12 pitch) to a tree where it would terminate about 12 feet off the ground. I'm sure that this mounting would physically be possible, but you all would know if it would even work on 10-40 meters. Looking forward to moving into HF and trying hard to avoid causing concerns from HOA and neighbors. Is this concept at all workable?
