| | | Posted by Aran Also, if you get caught, the government tends to get a bit touchy about people mucking around on their communications infrastructure. As in, "You're under arrest for potential terrorism" touchy, from what I've heard.
| Yeah, that is true, gotta hate those terrorism laws that can really by stretched, something to keep in mind, though not a huge concern for me. What I need to know for sure I guess, is whether this tower is a broadcast tower or a cell because if Craig is right about it being broadcast, I will follow the advice of staying away. I might have to go scout the base of the tower and check for signs, I can do that pretty easily, some closer pictures might also help some people who have some know on the subject identify the tower.

| | | Just found some assigned frequency information on the site I'm loooking at. (Edited out location specifics) Please note, these listings are all the same location.
(Lat: [REMOVED] Lon: [REMOVED]), Structure height: 91 m, Call Sign: WPDC495, Licensee ID: [REMOVED] Assigned Frequencies: 929.712 MHz Grant Date: 09/03/1998, Expiration Date: 09/03/2008, Cancellation Date: 03/27/2001 Registrant: [REMOVED]
(Lat: [REMOVED] Lon: [REMOVED]), Structure height: 91 m, Call Sign: WPDC496, Licensee ID: [REMOVED] Assigned Frequencies: 929.662 MHz Grant Date: 09/03/1998, Expiration Date: 09/03/2008, Cancellation Date: 03/27/2001 Registrant: [REMOVED] (Lat: [REMOVED] Lon: [REMOVED]), Type: Tower, Structure height: 91 m, Call Sign: WPFN659 Assigned Frequencies: 929.762 MHz Grant Date: 01/13/2000, Expiration Date: 01/13/2010, Cancellation Date: 10/28/2004, Certifier: [REMOVED] Registrant: [REMOVED] (Lat: [REMOVED] Lon: [REMOVED]), Type: Tower, Structure height: 91 m, Overall height: 98 m, Call Sign: WPGD504 Assigned Frequencies: 929.212 MHz Grant Date: 06/15/1998, Expiration Date: 06/15/2008, Cancellation Date: 11/02/2004, Certifier: [REMOVED] Registrant: [REMOVED] _____________________________________________________ Are these frequencies in the 900 MHz's very harmful?

| | | Well I've been waiting for a post that I can actually contribute some useful information to be my first on this very cool forum. This one should fit the bill. I've worked in broadcast engineering for over 15 years, seen hundreds of towers climbed, and climbed a few myself. From your picture I can't say for sure there is no broadcast antennas on it, but there does not seem to be any high power TV antennas, which tend to be quite large. Medium to high power FM would probably be the most dangerous thing you'd come across in a relatively small antenna. AM towers are usually energized, which means the whole tower is hot. Do not climb an AM tower! Luckily AM towers are easily identified because the guy wires have insulators. Also by law AM towers have to have a locked fence around the base. Microwave antenna (the big dish looking ones) are usually safe too if you stay behind them. Towers located in the USA that have broadcast antennas on them should have a sign at or around the tower with antenna structure registration number (ASR)call signs for the station on the tower, and emergency contact information of someone responsible for it. This is an FCC rule which may not always be followed, so use your best judgment anyway. If it is posted it will give you an idea of what may be on the tower. http://www.fcc.gov...ast-station-searchWith the FCC query tool you can find information on all broadcast stations. You can search by location, call sign, or ASR. This tool should even give you the station power level which is called ERP and is measure in kilowatts. Anything under a kilowatt should be harmless if you don't linger in front of antennas. There are also RF monitor alarms you can purchase and wear that will alert if the exposer is dangerous. They are a bit expensive though. http://www.sitepro...product_list&c=862This site also sells harnesses and other safety equipment built for tower climbing. 1. This is a low to medium power TV antenna being removed 2. This is a low power TV set up 3. This is a high power TV antenna I'm talking thousands of kilowatts 4. This is the coax feeding that high power antenna 5. This is a typical low power transmitter shack.
