[TowerTalk] Single tower and 3 monoband yagis -"Christmas three"

[Bill Fikis]

   Don,   In  a previous  lifetime I    Placed  my  20  mtr 
beam  above the 15m  beam.
             (  Both  5  el  monobanders)     There  was a 
Noticeable  difference in    the
      performance  of  the 15m  yagi...   both  antennas  had 
good  swr ,  but
   the 15m  yagi  was  VERY   bad ...........Bill / w2ay
