It's hard to find ANY apartment complex that would be considered, "ham friendly." I have lived in 4 different apartments in the last 26 years, and I operated HF and VHF/UHF transceivers in all 4 locations. Apartment management never found out. In one location, I had to operate from the car because there was no viable place to put up an antenna. I had one apartment where I had an attic that could put up a dipole and 1/4 wave ground plane for 2 meters. I operated on different bands with a tuner, and made good contacts, especially when 10 meters was open, like it is now. I had one apartment on the ground floor where I ran a longwire antenna in the rain gutter, running the length of the complex. I currently live in duplex style location. I have about a 40 foot longwire running the length of the apartment. Not the greatest situation, but sometimes you have to work with what you have. The lady who owns the company that I rent my apartment from was my kindergarten teacher back in 1980, so maybe she would give me a pass, but I haven't asked yet. My family owns a couple of farms about 2 hours south of where I live here in Kentucky. My brother is also a ham, so we go down there to operate Field Day every year, and certain contests. We don't have to worry about space for antennas or electrical noise when I operate from the farms. I hope to buy a house one day soon. Good luck with your apartment search.
