15 meters
A vertical dipole that is mounted on the outside wall of my house as you can see in three pictures below. The center at the sill of my third floor window as shown there is about 24 feet above ground (brick) level. It is fed with 72 ohm coax running down the wall through the same hole in the wall as the 20M coax into my shack. It is matched with the ICOM AH705 tuner not only on 15, but on 17 and 12 as well. I also have been using it on 10 meters lately with good results. So this one antenna serves me well on 4 bands. The neighboring house is only 6 feet away from my house at the place where the dipole is mounted. This shows clearly in the pictures. I used #16 stranded bare wire for this dipole.
