[TowerTalk] Steppir BI-directional mode

[Jim Thomson]

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.
