I am curious with those of you who live in apartments or HOA restricted communities do for antennas.
I am in this exact situation, i.e., living in an HOA-restricted condo community where putting an antenna outside is absolutely banned. I researched the antenna subject for a few months, talked with many other hams, both in person and online, and finally reached the conclusion that a magnetic loop antenna was the best compromise that I could make in my situation. And because I am also in the situation where I have virtually zero space for working on any kind of a build project, I decided that I would just go ahead and buy a ready-made magnetic loop antenna. Here is the one that I purchased:

This antenna is easy to set up, easy to tune, and I have had some remarkable QSOs with it, with the antenna sitting right next to my desk, inside of my condo.
I also run a 10m beacon out of my condo using an MFJ-1622 apartment antenna, which is another option you might want to consider. The MFJ-1622 does not work as well as the Alpha Loop in my situation, but you may get different results.
