Also, when you see that thing on the ground at the base of the tower, stay away ! It is related to obstruction lighting I think ?
Here we can see the baluns on the guy wires :

That's insulation for the tower. In AM, you can pretty much consider the entire tower frame to be the radiating antenna. That insulator is how far away you should stay from the metal truss, roughly speaking. Do NOT go into the shack beside it if the tower is powered. You will probably piss off the engineer who has to scrape your crispy bits off the expensive helix building capacitors.
If a 200-foot tower is rated at 300 MW, and you block 1/3 of the way around, you're catching whatever part of 3 MW wants to interact with water. Metal you have can also be affected... ask Joe about his phone dying near a cell phone antennae.

The only thing I would bother climbing is a guyed cell tower or a free standing lattice cell tower.

The entire structure is live. Even after being turned off, due to the earths field, there is still a potential voltage between it and the ground.
The dish-part is to keep rain from running down over the insulator (below the dish) and shorting it out during a rainstorm. The balls are for lightening protection, its a small enough gap that lightening can jump it but large enough the broadcasting energy can't. Theoretically, it's safe enough to get that close to the tower! But f*ck that, I wouldn't.

| | | | Seeing pictures of radiating tower masts, they almost always have a wooden fence around the base. Is that because a metal one would somehow interfere with the radiation?
Edit: it is.. From wiki:
| Mast radiators, as with all other equipment showing over 42 volts on exposed components within 4 metres of the ground, are required to be fenced in. Sometimes wooden fences are used in order to prevent signal interference, which could occur due to currents induced by radio signals in metallic fences. If the mast radiator is mounted on the top of the helix building, which must be over four meters in height; or the mast is grounded, with the feed being located not less than four meters above the ground, a fence is not required. Nevertheless it is always recommended to fence in any mast radiator in order to prevent unauthorized climbing. |

| | | | I have a couple questions about waveguides and coax cable used on towers and other devices.
It is possible for RF to leak from coax cables on a TV, FM radio or cell tower ?
Also is it safe to be standing near or touch a microwave waveguide ? I'm talking about those rectangular hollow waveguides. Not that I want to touch one haha but I'm wondering. Haven't seen one yet.
Also, what is that thing? I took a pic of it when I was standing in the middle of a tower :
I have never climbed a tower yet. I stood in the middle of several towers and climbed a few feet on the ladders but I'm not climbing anything without safety gear.
Highest climb hahaha

| | | | I response to the leakage of coax lines, yes and no. All coax (or Andrew Heliax brand which is pictured in your pics) most always induce leakage of signal, depending on the frequency it's carrying. Most cellular systems use the Andrew AWA7 or the old LDF7-50A heliax line, which for a 900 or 1.2G system, would only have roughly .00087 dB of signal leakage per 100 feet. Which is not much at all and a very good run. 
For waveguide systems, the old runs use copper or aluminum waveguides, wheras the new systems use the Andrew Heliax Waveguide line, which limits the amount of signal leakage by alot, and also has the nice jacket insulation that the older waveguide systems didn't have.
Overall, if you brush up on any coax or heliax line that has the insulation, you're fine and it won't hurt you at all. However, if it's the old waveguide systemwithout the insulation, I recommend staying away from that stuff unless you know 100% for a fact that the system is shut off or dactivated. They normally carry a minimum of 5kW of radiating power. That's enough to literally melt your skin off if exposed to the signals for an avg of 30 seconds.
I guess if peope insist to climb towers for kicks, just add the equipment and safety into your equations before you climb. If it's worth it, then go for it. But there are always risks, including those like myself who use harnesses and safety equipment on a non-active tower.
Good luck!

Looks like a junction box - just some wire routing stuff. Not all the things that look like coax/waveguides are. Some are just cable channels.

Mom: "No, he's at work"
Dad: "You sure? Some kid parachuted off a cell tower out there, I wouldn't put it past him."
Mom, "Of course not, he can't afford a parachute, and he'd be calling home for a ride, pissed off they towed his car."

I can identify with this: after a draining adventure with two non-UER explorers last year that ended with exiting into a street, surrounded by confused locals, it seemed that we had escaped without causing anything more than mass perplexity. About a week later, my mom emails me an excerpt from the weekly town paper's police blotter: "Sunday, 6:35 PM: A new trend in college pranks seems to be on the rise, with reports of from five to as many as seven college-age boys appearing suddenly in the streets, in broad daylight, as if from underground, according to multiple calls to the department. No arrests were made, as no crime appeared to be committed." Fortunately for my continued participation in UE, my parents still didn't know I explored, otherwise this could have been a disaster...

See the horn repeaters atop? That's a Long Lines bro. Never seen the tower construction like that before though.
Horns will be inactive but if there are any active cell transmitters stay 3-5 feet away minimum, more if you can (there should be a sign at the bottom detailing how close you can get.
This one was apparently more than 3-5 feet.
^ If you don't see a sign like this ... it's normally 3-5 feet.

Can anyone identify what type of tower this and/or what it might be used for?
i know it's not the best picture.
the location of the tower leads me to believe that it is no longer being used for anything, and i'd like to climb it next time i get the chance.

This was likely a GWEN tower. Compare with the drawing in this article:
http://en.wikipedi..._Emergency_Network
The giveaway is the extra set of wires radiating from the top, more than the three necessary for structural support. This "top loading" is used for antennas on longwave frequencies like those that were used by GWEN.
The list of sites in that Wikipedia article is not complete, there were at least 2 sites in Maryland, and at least one in every state. Some were recycled for use by the Coast Guard, others abandoned.

|  | | | I was very close the week before I left. Guess I'll have to wait until next year.
The lights wouldn't make you any more visible, its just that more people are looking at it in general when they have the lights turned on. I might just ask channel 5 to let me climb it next year, seeing as they are the only channel that didn't ask for permission before they used my barrel monster photo.
