RW> EV>> I forgot to mention I looked at my TV Antenna and it has One Boom,   
   RW> EV>> so it's a Yagi not a LPA.   
      
   RW> TW> It is not the Boom that makes it a Log Periodic. IT is the Director   
   RW> TW> elements.   
      
   RW>No, the boom is like a folded antenna with shortened radials; the twin   
   RW>boom is actually one boom, but the radials are stepped, one on one side,   
   RW>the next on the other side, etc..   
      
   GOTCHA YOU Roy this time. While the twin boom Log periodic popular some   
   are Single Boom and the Differeing lengths of the directors, Longest   
   near the radiating element and the shortest the tip of the boom(Single   
   or Dual)is what speperates them form a standard Yagi.   
      
   RW> TW> On a standard Yagi they bare al the same length like my VHF   
   RW> TW> Hi Band antenna I use to recieve Ch 8 & 10.   
      
   RW>You're using a VHF antenna to receive UHF digital stations 8 & 10? That's   
   RW>odd.   
      
   NO as I stated I am using a High Band VHF TV antanna. Low Band covers   
   channel 2 thru 6 and High covers Channel 7 thru 13   
      
      
   RW> TW> the Log Periodic has different director lengths with the formt one   
   RW> TW> being the Shortest.   
      
   RW>And they're staggered from one side to the next which is the reason for   
   RW>two booms (which are connected together). Note the electrical schematic of   
   RW>a LPA vs a Yagi. The elements are short to very long so that the antenna   
   RW>can be as broad-banded as required. Especially in a Television antenna   
   RW>that covers VHF channels 2-13 and the UHF channels 15-83, way back when   
   RW>there were more UHF channels than there are today. Cell phone service got   
   RW>the UHF band that 70-83 used.   
      
   Staggered on the twin Boom YES but they are NOT on a Single boom Log   
   periodic but the the elements are insulated from the boom and there is a   
   crossover connection at each Left and Righ Element pair as seen on the   
   page I referenced.
