Hi TT's:

I recently bought this yagi from my "main supplier" of
antennas and towers , is in very good shape, vy clean,
is the 20ft boom , there is another that is the LB
with 25ft, I know this is an old antenna and the new
techniques of modeling was not used on it,  also the 
4:1 balun to reduce the 200 ohms feed point,  is any
here that  improve a little from the original 10.5 DB?
gain that claim the manual ??? i get the manual from
the LB version and use the 1/2 inche elements  this
model use the 3/8 elements  with the plastic mounting
bases, 

any help to improve this antenna from his original
"gain "will be apreciated
