I have a large quantity of Cellular Band Pass Filters available.  The pass
band is 860-900 MHz (easily passes the output frequency of the cell system).
These are ideal for use with outdoor antennas that bring in many unwanted
signals.  I have not yet measured the pass/reject attenuation, but if you
are interested, email and I'll test one.

The filters are manufactured by muRata-Erie and were originally intended
for use in the construction of cellular telephones.  They are 1.5 cm
square, 0.9 cm thick, and have a mounting flange on the bottom that
extends 0.5 cm away from the metal enclosure.  The input and output 
leads are each 0.5 cm long.  These are a 3 terminal, passive device.
They are also uni-directional (marked on case).  Although designed for
surface mount, you can solder coax directly to the device or bend the
leads 90 degrees and insert into a PC board.

I suppose they could be used with scanners to reduce desense from
unwanted signals by placing them in an RF tight case with BNC
connectors in and out.  This could then be attached to the antenna
port when desired, but of course it would be unnecessary since NOBODY
listens to those frequencies with a scanner.  But since these are
intended to go inside cellular telephones, I'll just assume anyone
interested is designing / mfg'ing cell fones!

Price is $4/ea. plus $1.50 to ship inside the US by US Mail. (I can
send about 6 of these for the $1.50; they're lightweight)  I'm selling
these because I have enough to last a lifetime, especially since I
don't listen between 860 and 900 MHz!  For info - reply by email.
