Has anyone experimented with inserting a notch filter on a 450i 900
AP, for a specific 7 MHz?
All of the options I can find are for a wider 900 band, more than a
specific 7-10 MHz section, and cost $150+ a piece, so you're adding
$300 and some jumpers and 0.5dB insertion loss.

Dude, there's interference everywhere in the 900 band. Cordless
phones, baby monitors, security systems, smart meters, SCADA..
and the list goes on.

If you do 6 sectors, you're using the entire band and have
nowhere to go when one or two sectors is experiencing
interference. Or you have to drop down to 5MHz channel
bandwidth which sucks. This is why we do 4x90 clusters. Two
channels with wiggle room. Of course that's FSK's 8MHz
channel width. I think a lot of people have found that 7MHz
on the 450i works best.

No, I’m not complaining, I’ll use them. I’ll figure out

Well, if you want small... there's these, I'm not sure
I'd want to try doing channel re-use with them though.

I’m specifically interested in the 900Mhz, I thought that
was the 450i, I didn’t know it covered 5.8GHz also. I
also need maximum bandwidth off the tower although I
don’t know tower or other mounting locations yet to
determine if I need 360 degrees. I actually have more
problems with aesthetics and those antennas are going to
be an issue due to the size. Right now I’m interested in
throughput per antenna and what kind of throughput to
expect with GPS.

If you guys are talking about the 900mhz 450i 65 degree.
Straight from the horse’s mouth is the 65 and the 90 are
the same antenna. Just more role off to achieve the 90. I
have tested it outside of the 65 degree but within the
90. I was not happy with the results. One customer had to
be put back onto FSK yesterday until we can get another
AP up or a true 90 degree. Just would not modulate up and
finally dropped off completely.

I looked at the 450i and noticed the sector antenna is 65
degrees. Does that mean a typical tower installation
uses 6 antennas? In that scenario, I’m assuming 10MHz
channels if there is no interference. In that scenario,
what is the available bandwidth per AP assuming most
users get pretty good signal. Or is there a better way
to deploy the product?
