WB2MIC Multi-dipole 4-band sloper single feed
  
I've always wanted to try a multi-dipole antenna with a single coax feed.  Knowing that an open-wire fed single dipole would work, perhaps better, I decided to try anyway.  The images below are the details of the antenna I built on 03/11/06 and hoisted up on 03/12/06 as a sloper - 40 feet at one end and 10 feet at the other.  I added a 6-inch wide 6 turn coax choke and that helped with making the antenna trasnmatch  with the Palstar AT1500CV tuner on 12 meters.  I don't worry much about SWR as long a the rig is seeing a low SWR at the transmatch.  Though still testing out this antenna on the WARC bands plus 6, it works DX just fine on 30 and 17 meters.  Initial test results on 30 meters:
