Jejeje the 60x60 cpe trango antenna! Canopy anyone?
Now on a serious note, the real problem I forecast with this is on 5.3 ghz
and OFDM where you cant use a dish

Subject: [WISPA] M5580 feedback and Dish mounting help
The Trango M5580 is a great product and been working well from a stability
perspective and price point, and glqd to have it as an option. However,
there are several challenges to deal with.
There are two negatives that creates a third.
1) 8 db int antenna, so 7 db less than Fox5800.
2) No longer supports RF Threshhold command.
The range drops down to two miles, giving you a -74 signal, more easilly
able to survive the noise using DSSS.
However when upgraded to OFDM, I'm concerned about the low gain of the radio
being able to survive the noise with adequate singal to noise threshold.
I'm guessing the range will be more like 1 mile to have high enough signal
to support the high modulations. Unless of course the dish install is used.
This is where we make a savings. Using a inexpensive M5580 w/ dish apposed
to Fox-D.
The foxes without the dish was convenient because we could mount lower, on
the side of the wall or under eves. Now we are in most cases goingto be
required to mount on the roof or on the side of the house at the peak. I
hate drilling down into the roof, for water proof liability reasons, but its
likely that may have to start happening.
What we are finding is that most of the houses we are targeting, we are
finding that the peaks are taller than our 30 ft ladders can reach, and
often taller than our 40 foot ladders can reach. We are also finding our
underserved area, are larger homes with very steep peaked roofs, causing
safety issues. We often will carry a 20 ft section of ladder with hooks,
and lift it onto the peak as our method to climb. But when the edge of the
roof is up 30 feeet, its scary pulling the ladder up, to lift onto the roof.
Clearly a two man job, that takes care. What we are finding that we are
doing instead, is we are finding a way up to the peak of the roof, and then
we straddle the peak so we can safely manuver to the side edge where we
mount a Pole (with M-mount and contilever mount), and have DSS dish extend
over the roof line. Its can be difficult hangling down over the edge to
mount the bottom cross bar to stablize the pole.
So my question is, how are people optimizing this process? I know some one
makes a pre-made kit in steel, for this type of mount, without needing to
cut 2x4s. Whats the best place to find these mounts, and what thickness do
they need to be to adequately support the Fox Dishes?
I need to make the determination if we can cost effectively still mount to
the side of the house easilly for these installations, or if we have to
lower ourselves to Cable TV standard, and screw through the roof :-( And
at what point we are better off staying with Fox5800 SUs, apposed to the
timely and more costly install requirements.
Any suggestions to speed this mounting process is helpful. ( at heights
higher than 40 feet, for DISH mounting )
One of the guys at The Trango show had some suggestions on this, but I
misplaced the info I got from him on part numbers.
I was consodering upgrading to a bucket truck, but most cost effective
bucket trucks wont get us up to the 45 feet peak height requirement in most
cases. (walk out basements, with Step peaked roof, and multiple stories are
common here and killers of the quick install)
