    RW> Greetings Ed!   
   Howdy! Roy,   
      
    RW>> The DDRR (Directional-discontinuity Ring Radiator), vertically   
    RW>> polarized antenna....   
      
    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!   
      
    RW> When I looked at the photo of the FM broadcast antenna sold my   
    RW> Walmart, that reminded me of the DDRR. And basically, it is a   
    RW> Halo antenna with a reflector used to make it a vertically   
    RW> polarized antenna. The HF version uses the ground as its   
    RW> reflector, while we used a slightly larger ring to make our   
    RW> 27Mhz and VHF antennas. I even made one for UHF and it was   
    RW> mounted on a CB mag base so I could take it with me anywhere in   
    RW> the car.   
      
   Reading about the Wal*Mart FM Antenna made me visualize a flat sheet   
   of Hardware Cloth or Chicken Wire behind the Halo on that antenna.   
      
    RW> Dunno what happened to it since the move to Texas.
