This thread has [honestly] sucked lately -- so i'll spice it up with some tower porn....

I was in a tower site installing some new 5.8ghz links. Lookie Lookie...

Shot the link 26 miles with no problems --- we're in florida so there's NOTHING in the way.....

Holy Crap! 26 miles?? I never realized that it would be that far for 5.8ghz, I figured it'd 5-10 miles.

Why does the FM gear say 68 on it? FM goes from 88.1 through 107.9, why wouldn't it say that?

Great pics! Love it!

Because that is a Crown Broadcasting FM100 broadcast transmitter exciter and the front panel multi-meter is dialed to a setting that displays a setting not related to it’s operating frequency.

yep - correct ... it was displaying output wattage to the antenna.... 68 watts of FM power

I have never worked on or seen that many wires in one place. I know you need to be trained to work on that kind of stuff.
My question is. How do you ISOLATE what wire is what? The way I see it, EVENTUALLY the wire colors/combo will be the same..May be beyond my comprehension?

Theoretically everything should be labeled. Ideally there is a label on both ends of the cable throughout the entire system (any cross connects, passthroughs of equipment like SPD's etc) showing the cables to/from information. A lot of times people will use number markers on the cable or colored tape. We use Panduit labels which are generated from a spreadsheet with the appropriate to/from information with arrows pointing to/from directions. As far as I am concerned, this is the only way to do it.

Most of the time though people do not even bother to label anything so you just have to trace it all out.

Depends on what you're tracing. Telco wire sucks ass to trace. Many times it's not labled, and the only way to do it, is take it out of service at one end, and put a tone generator on it and find it with an inductive probe (Looks like one of those live wire tester pen things)

RF coax, totally sucks beyond ass when it's not labeled. You only pray you can find out by elimination, physically grabbing and yanking, spectral sweeps, you name it... I just finished cleaning a couple sites with a bunch of old antennas and coaxes on towers that were out of service and nothing labeled.

Anything else, well it's in between. Ethernet is hell to trace as well unless it's labeled, but at least it's more commonly cataloged than telco tends to be. It still involves taking it out of service if you need to trace it.

Ever trace a bunch of hardline feeds from a tower, that you have no idea what is on the other end?

That's a plesant day spent with an Anritsu....

NOT!

A wonderful NDA... And sadly I can't bitch, because I wrote it. It's well needed though for certain reasons.

Pardon my cluelessness, but what are all those 66 blocks and cross connects for? It looks like a small office building.

Many tower sites have loads of phone lines and other circuits going up to them. They can be for voice, data, auto-patches, remote monitoring, remote control, trunk circuits, test circuits, you name it.

Basically anything that can be carried over a phone line

Probably also lots of t1's. I see at least one multi-mount box on the side of the one picture, and maybe the bottom also, but i am sure there are more.

T1s are very common to tower sites. I know many that still trunk loads of cellular traffic through T1 instead of fiber or microwave backhauls.

So Australia has one up on you yanks then.

The vast majority of mobile base stations in Aus use fibre and/or microwave backhaul.

The Telstra Next G network is a prime example of fibre backhaul. Almost all of their base stations are connected via fibre running gigabit ethernet.

Vodafone/Hutch (3) and Optus have a LOT of sites connected via microwave and some via fibre.

Depending where you are, fiber is the more common/preferred method. But there's tons of sites out there that are so remote that bringing fiber to them is hell. So they just throw some T1s up and away they go.

If came right down to it... I would think you guys would go for microwave based back haul before using T1 lines....

Or am I missing part of this picture...

Many do microwave as well... The kicker is sometimes it's much cheaper and easier to bring in T1, than it is to fight with a shitty company (Cough, Bell, Rogers) to use space on their towers, when they are the only ones who can make the link.

It's a very closed market, in a difficult area.

That's the tower on Congress in Delray isn't it? Drive by it every day to work.

Neat to see what is going on inside of it. Thanks for sharing.
