OK y'all, stirring the selectivity pot a little, the logical
conclusion then, is that a notch duplexer is not all that bad. At
least not as bad as sometimes one would believe from reading some
posts here from time to time.
If a plain old simplex base station can work well without ANY
selectivity between it and the antenna, one could conclude, maybe,
that a notch duplexer isn't so bad after all.
Like I said, just stirring........ :)
