Driving back from Texas from Dallas across the top of the state there were antenna towers about 350-400 feet high every 5 miles or so. Nothing at the base but a little shack, anyone have any idea what they're all about?

I guess you would want a really long life bulb for the top of that apparatus.

Another one of the tallest towers around is in West Virginia. It is WVAH TV 11's tower located on Coal Mountain, which is about midway between Charleston and Huntington. It is easily seen for many miles from I-64. It uses the bright, white strobe lights. I was told that the length of the tower is 1,732 feet, including the station's antenna array. This figure is pretty reliable since I was involved in the construction of this structure back in the early 80s. It was touted to be the tallest tower east of the Mississippi (in the US, at least). I don't know if that figure is still true. The tower has a small elevator built into it with an equipment platform near the top.
In addition, Coal Mountain is approximately 900 feet above sea level (I know, not a HUGE mountain by some standards, but keep in mind that it is about 600 million years old, too!). Coal Mountain is also home to WCHS TV 8's transmitting tower (south end of the mountain), which is somewhere around 1,000 feet long and has red beacon lights. Been there a lot longer.
Originally, WVAH (stands for "West Virginia Almost Heaven") began broadcasting on channel 23 with an ERP of 5 megawatts! Signal got clear to Portsmouth, Ohio, which is close to 100 miles away! Due to "drop out" and severe null areas (despite the amount of power), along with the exhorbitant cost of the energy to run the transmitter, the station relocated to channel 11 a few years later at a significantly reduced output power. They wound up covering more area anyway!
Thought you all might find this interesting.
And I'd LOVE to stick my IMAX 2000 up there!

Gentlemen:I have been informed by a previous forum member that the tower I listed as being the tallest tower in the world is not close to being the tallest.I appreciate this correction and now I know not to believe everything I read. |

Hey guys, I don't want to stick my foot in my mouth, but I remeber reading about a tower in North or South Dakota that was listed as the tallest transmitting structure in the world. If my memory serves me correct it was listed as almost 2500 feet tall. It must have been a very tall base structure with a huge antenna coming off of it. I think I saw something about it in a book at my folks' house. I will try to look it up this weekend and get back to you guys next week about it. But PLEASE!!! Don't hold me to this, I could be mistaken! I'll get back to y'all!

You may have to verify this statement but I have been told that the highest legal tower in the U.S. cannot be higher than 2000 feet. |

Up near Hastings, Mich there is a HUUGE tower that stand perhaps about 1800 feet to the tip of the tower. I believe its some sort of FM broadcast station but theres a tiny shed at the bottom in a fenced in area that looks like an old outhouse and is hardley big enough for one person!! |

What kind of towers are you refering to? There are several commercial towers all over the US that are well over 2000 feet. I am not sure on what the tallest one is though. |

Ok, gentlemen, I have found the tower I referenced earlier. It is the KVLY TV mast in Blanchard, ND. It stands 2063 feet tall, and is the current tallest structure in the world. There was one taller antenna for a while in Poland that stood 2119 feet tall, but it has been destroyed. There is another tower that is planned to built in Missouri by Kohn Ind. that is going to be 2000 feet tall. There are not towers all over the US that are well over 2000 feet tall. There is a number of them over 1500 though. I believe the next tallest is located in North Carolina and it is 1800 and some feet tall. I just did the research and this is the current stats that are out there. If you find something that disputes my claim, post it nicely, don't flame me or be rude. I have never seen any of these towers, so I wouldn't bet the farm on any of this. But I hope this may be interesting to some of you. Could you imagine putting an 18 element beam with about a 1000 watts going trough it on top of that? I bet it would make all you techies out there tremble with glee.

Might want to check if they rebuilt that tower in ND in 1997 when I was stationed in ND we had an ice storm that took it down, the local emergency dept.'s had their antennas on it also and on the ham side I was part of the team that dispacthed for the Hosp.

Alright guys, check out this website. Acccording to what it says, it supports my statements. However if it hasn't been updated since 97', an ice storm may have very well taken it down. How in the heck can they put up a tower that tall? I don't think they make any cranes that large although I may be mistaken. But I sure would have loved to be on the site when they built it.
Anyway, check out this link.

Your persistence paid off although I believe Hamcber told me about a tower overseas that is taller.I could be wrong as my memory isn't what it used to be.Thanks for posting the website. |

God I'd love to Base Jump one of those towers!! Anyone else out there into skydiving? I talked to a guy once at a drop zone that had jumped an antenna tower a couple of times, he said once he got to the top he had to jump pretty quick because the metal D rings etc.. on his rig as well as the fillings in his teeth would start to heat up from the signal that was being transmitted!
