Well I don't know but the pac omni is at a price where it would not be
the end of the world
if at some point in the future it was replaced with sectors.
*Part No:* OD9-8
*Item Description:* 8dBi 900MHz Omnidirectional Antenna, N Female Connector
*Price:* $110.95
then an omni would be
fine.
Should be fine until I have the subscribers at the pop to justify
something better.
I'm only trying to get my foot in the door. I don't think it's possible
to do "the absolute best" right from day one.

Problem is I might only get 10-15 subs at these sites in the next year.
Lets say I can buy 10 APs. I'd rather have 10 sites with omni's than 5
sites with 180* sectors.
At 15 subs a site I'd have 150 subs on 10 omni's at $35 a month. That
is $5250 a month.
If I sectorize 5 sites with 15 subs that is 75 subs and only $2625 added
to the monthly income.
Back to reality. I can't afford 10 APs.....but still, I don't see
sectors as being such a great thing. What is the point of doubling the
cost of a pop for no gain of subscribers?
Back to my question. If a guy wanted to use omni's for 900. What is a
good choice?

We have a legacy 900 omni at 750' AGL. It really reaches out and touches
remote customers, but it is visible to every other cell in the region and
affects channel planning. Stick to sectors, they might be more expensive
up
front but long term you will have more options.

Due to the eirp limits at 900 (36dB total) your antenna choice really
should
take into account the radio gain first.....
Having said that, a lot of people put in the high gain 900 omni antennas
and
don't seem to have much trouble with them.
I agree with the sector idea though.
The 900 that I'm using now is trango. They have almost got the full eirp
built right in to the radio/antenna system as it comes from the factory.
The down side is that it takes 6 ap's to cover 360*. That can get
spendy.
Especially if you pay rent per antenna.
As a rule, we are sectorizing more and more sites these days. Even the
ones
out in the sticks. There are too many other users out there showing up
all
of the time.

Hello Brian,
No more then 8db in my playbook anymore. And horz. if at all possible.
Sectors on 900 is the best way to go too.
I got an Antel 11db with downtilt that I would sell if you really want a
vertical omni. Heavy duty antenna.
