We NEVER climb without a second person on the ground, that is also equiped

Hi All,
I think we finally have this all figured out. Now I just have to figure out
how to fix it.
We've been up there for over 6 years now. It's certainly been a problematic
site though. Constant channel changes (we have 3 competitors a mile away
and pick up hundreds of ap's from in town)
Unless it's changed in the last couple years a cage is good for 20' in
industry. There must be a landing every 20' and the next ladder must be
offset and 20' to the next land. more than 20' to a land you must tie
even if there is a cage. There was an exception for overhead crane
operators
We also colocate with an FM transmitter. Only 1300W though. we also
had interference on our Ethernet lines. We solved it by moving radios
away from the FM antenna (3 feet or so on a 90' tower) We also
installed ferrits which helped (I actually used a conduit pipe).
Grounding the cat5 helped too.
We had a site with a 1000 watt AM Hotstick about 100 feet from another
tower. We ran the cable (non-shielded outdoor rated) and crimped the
end at the top of the tower. The installer all of a sudden, felt a
burning sensation on his thumb with that wonderful smell of burning
skin. Guess
Brian,
Why would you want to add a safety cable to the cage? I'm on several
legs with the cages and they seem great. I usually just lean back to
take a break while climbing.
It seems like an unnecessary bother, and something else to get in the
way while climbing the ladder. Just curious
It also sounds like there is a new leak in the waveguide. One more
thing you might try is to move the cable from leg to leg on the tower
so that you variable length sections that do not resonate at 350MHz or
~100MHz (FM transminssion).
On Wed, Jan 7, 2009 at 11:16 AM, Adam Goodman
Think wavelength.
AM wavelengths are hundreds of feet long.
There is a giant reactive near field around the AM antenna.
(Electric fields and Magnetic fields)
Your cat 5 was probing the electric field at two different voltage points.
For AM broadcast frequencies, you can actually take a volt meter
Well if your Tranzeo won't let you log into it then that sounds like an
issue that needs an RMA and personally I can say that for an issue like that
they have never denied me the RMA.
Now as far as general Tranzeo lockups I think that all has to do with
grounding your CPE. I almost never have to
Spending less than $1k on rescue
training per employee is pennies compared to the life of our employees.
I fully agree. (when talking about employees).
In my case, I'm the climber, and company owner and OSHA exempt because of
that.
I prefer not to subject my empoyees to risk, unless

You technically shouldn't be able to fall with a safety cage.

Interference protection is exactly why I went with 90*. Not that there's

The omnis are only for small areas, of a half mile or less.

It hasn't happened yet, but I'm hoping I have the good sense to stick
out an arm or leg and jam myself into the cage. Probably very painful,
but no long lasting damage?
Usually I have a backpack on, and have to climb the ladder more
vertical than normal, just to avoid dragging on the cage.
Don't worry. If you fall the chances are very good that an extremity will get
jammed into the ladder and you will be all nice and rolled up in a ball wedged
between the cage and the ladder. And the extremity that is now broken in 10
pieces will be above where you are so the rescuers will need
