[TowerTalk] help identifying antenna

[Jim Hoge]

Greetings,
   
  Can anyone help identify this antenna? It is a ~108-1300 mHz log periodic with a boom length of 54", longest element of 55 3/4", shortest element of 3 3/16", the booms with the shorter elements are 1/2" x 7/8" aluminum channel, the other half of the boom is 5/8" x 1 1/8" aluminum channel, element 1 is 1/8" copper, elements 2-14 are 3/16" aluminum, elements 15-20 are 1/4" and 3/8" aluminum tubing, the boom coupling stub is a copper coil, and lastly, there is a warning sticker on the boom to mast plate that has the Create logo on it. Any ideas as to a model number or gain and directivity information?
   
  Tnx,
