Greetings Ed!   
      
    RW>> The DDRR (Directional-discontinuity Ring Radiator), vertically

    EV> The Handbook I brought up here is the 1976 Edition and I can see a   
    EV> VHF Halo that looks Vertically polarized on page 330 but it doesn't   
    EV> look anything like the 6 Meter Horizontally polarized Halo I used   
    EV> with my Sixer.   
      
    EV> I will go see if I have a 1967 Handbook to see what this here DDRR   
    EV> is all about.  Thanks!   
      
   When I looked at the photo of the FM broadcast antenna sold my Walmart,   
   that reminded me of the DDRR. And basically, it is a Halo antenna with a   
   reflector used to make it a vertically polarized antenna. The HF version   
   uses the ground as its reflector, while we used a slightly larger ring to   
   make our 27Mhz and VHF antennas. I even made one for UHF and it was   
   mounted on a CB mag base so I could take it with me anywhere in the car.   
      
   Dunno what happened to it since the move to Texas.   
      
       Have a day!
