Running an End-fed Multi-Band Ham Radio Antenna from an Apartment

I decided to run an end-fed multi-band antenna from my terrace apartment. I needed my son to hold the ladder, so I asked him to take up some video clips with his telephone to use in the video. The only obvious tree was at the bottom of the hill, which meant the entire 10-meter antenna was directly above the stairs and very close to the building. After looking at it, I decided to stretch the antenna over our "garden" instead, since I could use the same wire mesh "ground", coax hole through the brick foundation of our building, and dubious iron stake that I had pounded into the garden. I just figured out how to use the antenna tuner this evening, so I haven't actually worked anybody on this antenna yet.
