I moved into a retirement community several months ago and I don't have many alternatives for a SWL antenna and earth ground either by the HOA antenna regulations, no dirt for an earth ground rod, no metal water pipes for grounding or any perceptible grounding rod for the electrical service panel on the side of my house. Only thing I have done is I constructed a stealth dipole slinky antenna in the overhead inside my garage. For a ground, I have been utilizing an old and not recommended trick of using the neutral contact on an AC outlet. It actually works but a crummy way for a ground. I could use counterpoise grounding but there is no area around my house as it is all concrete walkway. If there are any alternative DIY antennas and grounding ideas that I have missed, please let me know.
