Re: What type of towers do you use?
"A 10 foot mast above that would put you around 92 feet AGL."
What does AGL mean? I was confused because the tower is like 65 ft tall and 10 more ft would be 75ft.
Thanks |

OK, we can do the math...
Water tank = 65 feet
GME tower = 17.5 feet
mast = 10 feet
65 + 17.5 + 10 = 92.5 feet. |

I thought the roof mount was it. I thought that cancelled out the mast but I do remember now you add masts to the roof mounts.
From that 17.5ft mount how much of a mast could I add?
Like when working in the antenna's or upgrading you just shrink the mast down and then back up when done correct? |

Because of the narrow spacing og the water tower legs, the angle of the guys limit the height. I have some real concerns about how strong the top of that old water tank is to be able to hold the GME tower. You may want to weld up a pair of saddles to reinforce the tank. The most you could collapse the mast down into the GME tower is 17 feet. Depending on what you mount to the mast, what guage the mast is, and where you guy it, I would not put more than a 20 foot mast on it. Some of that 20 feet will stay inside the GME so you would only have around 15 feet of additional height.
When I mentioned a popup mast, I did not yet see your water tower and in my mind's eye it was much larger. As I mentioned earlier, standard guying practice puts the base of the guy at 80% of the height. You certainly don't have that. |

At least not in that area.
I think my best bet is to start with this tower here. Hit who I can and upgrade as the demand increases.
When I need a new tower I will go for the full 190ft guyed tower and put it on my land in my back yard.
But then again according to RM maps I have been getting I might not be able to hit many people so a tower might be a must first off. I will have to debate this.
Concrete would be a lot just to set the guyed tower base. Do they not burry it in 5ft of concrete? Its what I saw on a pdf file that was linked here.
If I use my tower I will just make a homemade mast, brace it up well and put some sectors up there and have fun. |

Look at the loading characteristics. These towers are "over-engineered". They seem to be satisfied with that. If they are happy...!
Sometimes you just don't want to be concerned with stuff you have "already done". AN Wireless Towers are that kind of tower. Do it once...move on to the next thing.
(I have spent A LOT of time looking at towers lately..!)
Pricing is pretty good...!

| I was doing some long term planing the past week or so. Stumbled across AN after looking at Trylon and others. After looking at the specs of their HD series I almost feel in love. That's one heavy duty dude, and just what I was looking for in a 60-80 foot self supporter. Short of a tornado, it reads like it's gonna stand up to anything mother nature throws at it. Of course within loading specs and proper installation. |

To bad they cant put up a tower bigger than 120ft. |

| I think once you get in to those heights with a self supporter it's more of a custom build thing at that point. Of course there are companies that will accommodate you$$$$ for that need.  |

| Rohn 25 is good to around 125ish feet if you follow specs. Nice cheap and good guyed tower.
You can get some good 190 foot free standing towers. As mentioned before 200 feet and above requires FAA paperwork, etc. Plan on a year or so to get approved. If you go this route you really need someone who has done the process before.
I like ROhn 25/45 because they are easy to put up, and cheap enough. IMHO 10 120 foot towers give you better coverage that one 300 foot tower and costs are pretty close.

| From what I have been told, (we do towers a lot) if you can afford the Rohn 45 you should put it up instead. There are a lot of options that open up when you put a 45 in. More antennas, it can support larger dishes, plus you might have enough expansion room on it that you can resell space to others and recoupe some of the cost that you put into it.

Williamsport, IN | 45 will hold more for sure. 25 is fairly easy to find though. Most houses, at least in the midwest, have rohn tv towers. The majority of them are either cheapy rohn tower or rohn25.

I am sure 10 smaller towers would have good coverage or better than one big one as this is what cell co's do.
But wouldnt it cost a lot more?
I mean it would require:
LAND(rented for what? or bought say 1 acre=4000 bucks)
More Radios and antenna's
I guess you dont just put up a repeater on all the towers just some? or all? Or you would have to get a new connection to each of them by FAST dsl or fiber.
Power hooked up to each tower so more of a power bill. Considering these things use like no power it wouldnt be much.
Do people just let you put towers on their land for cheap or do they demand like 1000 bucks or so like they would with a cell co?
I guess saying you would get free internet isnt going to be enough to warrant a 120ft tower in their back yard and maybe your visits here and their to check up on something or whatever.
I guess you could always buy land. At 4k a acre factor in 40k plus the cost of 10 120ft towers(6k per tower?) 60k for the towers and then the radios and 4 sectors on each tower? so add in another 8k for that.
Grand total:
108 thousand or so.
Give or take. ha ha
Of course you would do this as demand increased. |

| Well, that makes a decent starting point and all, but you would think that they would have planned for when they got bigger.... 
Damn, would that thing have bigger issues with wind loading or just bulk weight????? lol

Anwireless seems good for shorter stuff, but i cant use this past 70ft
Sabre towers are what I am looking at now for anything over 70ft (county requires 90mph wind loading) Prices seem good.
In both cases I am looking at self-supporting, and this is the first tower I am putting up. Everything else is either existing structures or aquired.
Do most of you put up your own towers or rent off others?
I wish 1 acre = $4000 here! |

Scout around for some local water towers. I know you posted a pic of one in another thread. You may be able to get from it to others. Most around here are between 70' and 100', so they are viable options. I am currently working with a local water dept manager to try to get on several of his. I'll post the results...
