Topband: Bandpass filters for receive antennas

[Larry]

I have been following the discussion on front end relays with interest, 
and I was wondering
what sorts of bandpass filters folks are using for receive antennas.  
Right now my BOGs don't
have any.

I know of the W3NQN and similar filters;  I have a set for 80-10 that I 
use for Field Day.
I suppose I could make or buy a 160 BPF, but am not sure what effect 
this would have on receive.
I also have a set of coax stubs, and was wondering whether anybody uses 
stubs for 160.
Obviously, this would be a LONG piece of coax, but it would probably 
reduce out of band signals
by ~18 db IIRC.  I would be interested in what experience the members of 
the group have had.
