[TowerTalk] Steppir BI-directional mode

[Doug Turnbull]

Dear OMs,
     If I am not mistaken the SteppIR 3 element has a bidirectional mode and
it does have gain in both directions.   There is no need to retract director
and reflector.  I use all three modes forward, reverse and bidirectional in
contests regularly and find it most helpful.   My SteppIR is the 4 element
model with trombone for 30/40.

Why not retract the reflector and director and use it as a dipole?

If you configure the 3 el steppir yagi, so it has a DIR on each end of the
boom,
and the DE in the middle,  I assume its bi-directional.   But does it also
have 
BI-directional gain ??     Like 4 db gain in both directions ?   I cant find
my 
copy of YO,
so I have no way to model this.   If it does have bi-directional gain, I can

see where
it would come in handy, under certain conditions.
