[TowerTalk] 40m wire/city lot

[Mike Bragassa, K5UO]

What worked great for DX in 2 previous homes w/ similar size lot  restrictions, was a full wave delta loop, apex up,  low corner fed w/ 1/4 wave 75 ohm to 53 ohm to radio. You must have about 50-60 feet of height in the center to string this up and not choke people in your yard, of course. If the choice is to string it up such that you are little bit (key word: "little bit") short of stretching it out completely; I have used "property-extenders". Put up some TV tubing (1.5"~) at the property line on each side and tie of the loop. This was an excellent DX antenna; only improved upon when I put up a 2 ele yagi on the tower.

  I need advice for a 40m wire antenna in my 40ft/12m (E/W) x 144ft/44m
  (N/S) city lot, bordered by power and telco lines along the western side. 

  At the moment, I'm using an 80/40 Off Center Fed dipole (made by
  Fritzel), and for contesting it is, well.. mediocre!  Adding a rotatable
  dipole element to my roof-mounted C3-SS is, for the time being, a
  non-starter. I have a 160 inverted-L with 26 radials. 

  Thoughts, comments, suggestions?

  Thanks in advance!
