I dont think its  that  simple Andy ,
 
16 ft is  not  much  for  136 ,  and = the =20 loop  runs  up from  the  feed  point , which I = think  is  a  corner ,, so  at  what  = point =20 is  it a radiating  element  and =20 which  point  is it   top  loading

I wonder  what  exactly  is  = radiating Chris=20 ?

what  to  you  estimate the  beam  = pattern=20 to  be ,  I have the  idea , south  to  SV is = down ,=20 compared to  say  North TF ? , the  levels  into=20 Iceland  are significant=20 = ..
