The nicer the antenna, the more critical the aim is. A cheap 900 sector
will create a forgiving coverage pattern. A nice one like Tiltek or MTI
will have a well defined coverage pattern in the vertical direction.
Personally, I wouldn't put 900 that high on a tower, as it would receive
too much
We don't do this, as we have radios at various heights on the tower.
Here is an example of our antennas being at different heights:

This uses mostly coax except for hoz antenna on a standoff which uses

I don't post on DSLreports, but here's my opinions with the various stories
mentioned here and the sometimes illinformed commenters.
1. Painting all broadband providers as greedy isn't accurate. Greed is part of
the problem, but not all of it. Nothing unique about that regardless of the

I have not used MTI omnis. I have used their 900 horizontal sectors
though. They are rugged and have clean cuttoff in the vertical pattern,
good for sites where accurate downtilt is important to prevent
interference. Performance is good as expected, probably comparable to
other better
What exactly does the FCC logo (captial F, capital C, lowercase C
inside the big C) mean on a piece of electronics?
I've got a circuit board here (not a radio, but a networking device)
with the FCC logo on it and am wondering how to find out it's
certification information if that's important.
This happens right in my house. Since installing lots of extra ethernet
wiring, my ability to scan in the 2m and 150mhz areas has definitely
been hindered by all the off noisy channels. It happened because I
haven't bothered to use shielded cat5 at home.
At tower sites, we use shielded only.
That's definitely overlooked. We basically don't have a choice and CAN'T
install anymore backhauls in the 5.7-5.8 band at many of our tower sites
as the spectrum just isn't available. It's used for a mix of p2mp or ptp
links. And it's been that way for many years for us.
We have freed up some
I'm suprised nobody else has mentioned this...
hosts.allow/hosts.deny
It's simple, and dosen't depend on the firewall software to be running.
hosts.deny allows you to deny access from all IPs (or specific ones)
hosts.allow lets you override the deny file with the IP ranges or less securely
