      >Never heared it called a double discone but I use a discone that has a center element and it works great. I hear every county in the state on VHF as well as other states. Even my HP1 picks up Ft Wayne 90 miles away and Louisville Ky more than 100 miles away. Great antenna but I don't use the Radio Shack version but one that's around  $150. This thing survived a tornado while the scantenna didn't survive 50mph winds even strengthened.

      >>Well thanks a lot Joe... you just made my decidion that much harder ;)
      >>Now I'm torn between this thing from England, a single discone with a vertical element, and a discone without the vertical element (and that's just for the local signals I want to get with an omnidirectional antenna, I'm not talking about the directional yagi issue to Springfield).  It would probably be better to get a discone with the vertical element, but I also have a big oak tree very close to where I want to put my mast, and if it grows any, then I'm going to have an issue with a tree.  If I had an antenna without the vertical element, it would let me put the mast that much higher and stick the single discone on top without having to worry about that extra 4-5 feet of vertical element touching the tree for now.
