Tranzeo gear supports 10mhz and 5mhz channels on their radios made in the
last 2 years. I am using them in 10mhz channels talking to a Mikrotik AP and
it works great!

What 802.11 gear doesn't? Tranzeo maybe..?

Thats a great idea! Of course, you gotta have equipment that supports
smaller channels. Egads, another items for my "to do list"!

That's assuming you're using 2.4 and 20mhz channels. I feel it is
only wise to use 10 or even 5 mhz channels.
You drop those laptops that can see the AP and think they can get
service. You cut interference in half and focus the power in half the
bandwidth (bit more coverage!). You can only use things that can use
the smaller channels.

After my last comment on this about the omni, I'm hesitant to give out
advise but here it goes anyway:
My worst operating tower is quad-sectored. With 2.4GHz it's best to
stick with tri-sectors since you only have 3 non-over channels. Just
my two cents worth...

I decided to just upgrade the whole thing and install sector antennas.
It'll eventually go that way anyhow. This spot is the farthest out we
reach
but last week, out of nowhere, the calls started to come in from that
area
asking about service so I guess a real upgrade is in order. I have a
set
of
2.4 sector antennas that have been sitting around unused so I guess
that
can
be the home for them. The 5.8 however, any suggestions on that for
sector?
Again, going into the 600a routerboard, R5H cards.
My 2.4ghz sector antennas are 90 degree, so we'll be using 4. If we
use
1
card for each sector on the 2.4, then go with 3 antennas for the 5.8
and
use
our Ubiquiti XR5 for the backhaul, that's going to fill up all 8 slots
on
the 600a. Never been to that point before, will our 48v POE run this
whole
thing or should I just add another routerboard for the 5.8 and the
backhaul?
My head is telling me to just add the board but the wallet is running
away
from me............

If you've got to go 10 miles, then you need gain.
From the website.
*2.4 GHz 24db Directional Parabolic Grid WiFi Antenna*
*The Directional High Gain WiFi Parabolic Grid* WiFi Antenna offers
24dBi gain at the connector and a tight 8 Degree beamwidth. The high
gain wifi antenna is an aluminum die cast which is then powder coat
painted for added environmental protection. Because of its grid design
the antenna offers excellent wind loading characteristics.

Marlon,
Not sure what you are saying here. According to the vendors
specificatons.
Teletronics 15-124 - 19DB horizontal w/8 degree vertical beamwidth.
Tranzeo TR-24H-120-16 - 16DB horizontal w/6 degree vertical beamwidth.
Yes it is odd that the Teletronics claims a higher VB, but then again
it, it cost a lot more and should be a better antenna, as I believe
gain
not only comes with narrowing coverage (sector width), but antenna
design.
Regards
Michael Baird
Gain only comes from narrowing coverage with antennas.
If there are both 120* antennas you can't have HIGHER gain with
GREATER
coverage.... It takes half the coverage area go give you twice the
power
(3DB of gain).

Not ,the same downtilt angle, same percentage as the old one. The
previous antenna was a Tranzeo 16db w/6 degree vertical, the
Teletronics
19db has a 8 degree vertical actually larger VB then the 16db at 6.
They
are both at .3 degrees downtilt. The only reason I mention the VSWR
is
because the teletronics VSWR is 1.1:4, vs 1.5 on the Tranzeo. The
Teletronics is down about 6db on the CPE side for all the clients on
the
test sector, on the AP side it's the same. I tested multiple tilt's
as
well, between 0-1 degree was the best on the CPE side.
Regards
Michael Baird
First thing that comes to my mind reading your post is that you
installed
a
higher gain antenna which means your vertical beam is going to be
narrower
(sometimes higher gain is not always better). Being that you
installed
the
antenna with the same down tilt angle your missing the mark because
you
have
a narrower vertical beam.
As for the VSWR nothing really considered too low. If your VSWR is
higher
then 1.5:1 then you have a problem for sure.
Personally never used or tested TT's 15-124 antenna but have sold a
few
of
them with no complaints on it as far as I know.

I picked up a Teletronics 15-124 19db horizontal antenna for
testing
and
deployed it in place of a Tranzeo 16db Horizontal (TilTek?), using
same
pigtail and radio. With the clients on this sector, the AP side is
the
same, but the CPE receive side seems to have suffered with this
larger
antenna. Nothing was changed other then the antenna, aimed to the
exact
same degree, tilted the same percentage of vertical tilt, and so
forth.
I'm thinking the antenna isn't very good, or it's VSWR is too low
and
I'm getting some power reflected from the antenna. Anybody have
experience with this antenna, or these scenarios?
I expected this bigger, more expensive antenna to gain all across
the
board.

Michael Baird
