What about traps? Seems like a cool device would be an RF graphic
equalizer to tune each channel to the perfect level. And for the rotating
mast, have a graphic equalizer that changes with antenna direction.

Seems to me that to design an RF amp that is tuned to
a specific frequency band, in tandem with the IF stage,
to improve selectivity, requires either that this
more expensive beast be incorporated in the receiver
itself (increasing cost) or that it be added as an
external device, used as needed. But such an external
device would then require a signal from the receiver.
If done as such an external device, it becomes
cumbersome or even unusable for any setup that
incorporates recording devices or multiple receiver
hookups of any type. Unless the multiple receivers are
contrained to receive the same channel at all times.
So bottom line, in my view, tuning a masthead or
similar external antenna amp is not the right way to
go.
Anything wrong with dual conversion tuners? They can
accept wide band RF amps without paying the
consequences. Or just build the fancy RF amp into the
receiver.
