[TowerTalk] Interaction with the Optibeam 16-3

[Cqtestk4xs at aol.com]

Anyone out there using an Optibeam 16-3 tribander in close  proximity  to 
either an M2 40 4MLLDD or an Optibeam 40 meter Yagi?  By  close proximity I 
mean around 10 feet.
 
Any interactions noticed, especially 15M resulting in SWR and gain  issues. 
 If so, were you able to resolve them, and how?  Any comments  would be 
appreciated.
