[TowerTalk] Interaction with the Optibeam 16-3

[john at kk9a.com]

There is a big design difference between a linear loaded M2 and a High-Q
coil loaded OptiBeam with detuning stubs, however I think neither antenna
is resonant on 15m.  I do not see any issued with the proposed layout.  I
am sure that DF2BO would be very responsive if you asked OptiBeam this
question.

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.
