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

[Wayne Kline]

 IMHO    with the  tri band antennas  manufactured today.....   the Christmas's tree  loss from  interactions 
 
over come there  Mono band  gain.......
 
 At my old QTH I have two towers. a 10/40 combo and a 15/20 combo    
 
YMMV  Wayne   W3EA
