   this is somewhat on the topic of HAM but the actual use is not... i don't know   
   where to look for the information i'm seeking...   
      
   here's the scenario:   
      
   i need to make an external UHF HD antenna...   
   i do not have any funds available...   
   i found plans for a UHF antenna online and printed them out...   
   they are using some copper tubing that is wrapped half around a 26inch bicycle   
   rim for shaping...   
   the bicycle rim is only for shaping... it is not used for the actual antenna...   
   there are two halves each making one half of a circle...   
   the two halves are mounted on PVC members to hold them...   
   the circle is horizontal to the ground...   
      
   so in simple terms, this is a dipole antenna that is circular so as to be   
   uni-directional...   
      
   what i want to do is to make four halves and mount the second two 90 degrees   
   out to avoid any (slight?) blind spots as well as to provide more area to pick   
   up the signals... what i'm not sure of is how far apart the two antenna   
   circles should be mounted from each other or how long the inter-connecting   
   wires between the two circles must/can be...   
      
   i'm taking the idea roughly from a turnstyle dipole antenna that has 16 bowtie   
   halves where the bowties are a specific distance apart... and cross wired from   
   bowtie half to bowtie half... i don't know the proper terms for these cross   
   wires connecting the bowtie halves, though...   
      
   i was (slowly) in the process of making the bowties (from some 10/2 electrical   
   wire) when someone (don't ask, bad shituation) took all my copper and now i   
   don't have any to build even that antenna any more... i also wanted to make a   
   simpler antenna... i absolutely want one that is unidirectional because i do   
   not want to have to go and be turning the dang thing just to watch different   
   TV channels... our existing rotor is dead and i'm certainly not in the   
   position to purchase another one... so a friend has offered to provide enough   
   copper tubing/pipe to make the antenna and if it works well, they want one,   
   too...   
      
   so, two stacked circular dipole antennas with one circle turned 90 degrees   
   around the pole axis from the other circle... how far apart do the two circles   
   need to be? how long can the cross-connect wires be to link the two circles to   
   the balun/adapter where the 50ohm RG58 connects?   
      
   here's a link to an antenna that is very similar to what i'm looking to   
   make... i'm just looking at doubling the number of circles and connecting them   
   together properly...
