[Equipment] Yet another T200 bites the dust

Click for full size
I have only one Trylon T200 in the network and I have very little on it. They are somewhat notorious for doing just exactly what you see here.... moral of the story don't overload your towers, and if you do, expect them to look like this if there's a good wind

Those dishes at the top look quite large for the tower...

That looks like too much loading for that tower. That being said I had a 72ish footer with a 2 2' solid dishs @ 10 and 12 feet and 1 omni at the top fold over between section 2 and 3.

We have 2 of these in the grid and I fear them with a passion.

I pray they never fold with the climber on top.

No just co-lo'd there. There was a good wind the day it happened. Probably 60 mph peak, but just the same: if someone aims for a class 4 installation they can expect to get class 4 results... and the T200 shouldn't make class 3 no matter how Trylon twists the numbers - they are scary beasts. Seems they like to fold at section 7.... which if you climb them it gets sketchy from Section 7+ and I'll climb some pretty crazy stuff. Use lock tite, or check them every three months or they'll just unscrew and fall over anyways.

VOX - we've had this conversation before

I think they are 32 db Rockets without radomes... apparently a bad cost savings idea

Ouch that really suck's.

We put our backhaul's lower on the towers to keep the wind loading on the tower down a bit.

Just a trip to the home depot and our scrap pile and we threw together a mount for the rocket dish to go to the side of the tower.

If you want to see an example of what we do here is one below.

Dish without a radome is a bad idea...the radome improves the aero qualities significantly.

Durham Region and Clarington Regions.

edit: I have one tower in karawatha lakes as well covering cresswell and an expansion plan for there. I will probably end up using EORN to get a lan extension to my main pop for the Karawatha lakes side. I only have a continuous 20-27 megabit's half duplex roughly feeding that part of my network right now. Hopefully my link in will have enough bandwidth to last me long enough till I can get fiber there.

Same here - omni on a short stick or panels near the top and any Parabolic's are lower down.... back to back solid parabolic's at the top of a tower = bad idea. T200 in general = bad idea...

On the topic - I have yet to see it for myself, but there's another ISP near Kemptville who has apparently taken a Goldenugget top section, flipped it upside down and used the top collar to mount it on top of a pipe in the top of a DMX68 :-0 The reason : he needed more height and wanted to have more mounting space than a pipe would provide.... I really need to get down there and take a picture of it if it's still standing

I have inlaws that live down your way and frequently go there. The wife does all the driving so I get to rubberneck at all the wonky tower and mast installs. What I see never ceases to amaze me and I often wonder if the cowboy that did it is someone on this forum.

I mean, the stuff defies all common sense and the laws of physics! I guess for only so long, eh.

Nope never seen it then. Just saw on your website where you are, I dont get up there too often and only to fix the odd LED sign.

Heh you don't see many of those around these day's, Did you fix the broken led sign for paddy's market by chance ? (it was broken for 3 month's once and is the only led sign ive seen in the last 10 years)

Also my site is out of date I need to get around to updating it. I have many more towers since then .

Doesnt sound familiar, I mostly do the newer colour LED stuff for commercial properties and live events like the "jumbo tron" in Rogers Centre, BMO Field, electronic billboards, etc, and the pic is what we just finished installing 2 of at Maple Leaf Gardens! Yes they will still be playing hockey in there!

Sorry, back on topic.

For those that wanted to know what the H3ll I mean by an upside down gold nugget...

As I said above I have not personally seen it yet but I've spoken to those that have and a very poor picture on a cell phone and it pretty much looked like above from what I could tell.

I have NO idea what you'd need to be smokin to climb such a thing.

Not what I want to hear. Was thinking of putting one up at my house to get above some fast growing trees. I need it to support two dishes and was considering an 8-bay bow-tie at the top to pull in some OTA from 150 miles away.

I don't know how you guys do it. I see hams and whatnot climbing these skinny-ass towers. You could never pay me enough to go up one of those. Guyed or not.

Freak wind storms mind you. But Im not sure Id ever put 2 dishes on one at least nowhere near the top. Hell with my fat 190 pound ass on the top of one it feels like its gonna fold over.

Heh I saw a DMX medium duty (My site #6 is the HD series) with 5 added straight sections (yes 5 the guy who ran this wisp was clueless) with no guy wires survive a tornado less then 600 meters away that tor a path through a corn field around the tower grossly overloaded with 6 grid antenna's and 5 or 6 sectors.

Ive also seen "golden nugget" tv towers go down. One of them was only 1.5 sections above the roof just a vhf/uhf tv antenna yagi and nanobridge 25dbi it came right down on the roof.

DMX towers are wicked, even the most solid golden nugget tv tower I have 8 feet above the mounting point height isn't as solid at the top as a properly built DMX. Site#6 don't even sway on a windy day if you go to the top and shake it real good.

I would not recommend putting anything but your tv antenna at the top. Last 1/4 of the tower is much more flimsy feeling then the rest of it.

Also calculate your wind loading and ensure you do not exceeded what delhi/wade antenna says the DMX your building can handle.

I only need about 40 feet for the dishes.

That should be good but keep in mind to keep the wind loading to what the rating on the version of the tower you have.

I've a DMX68 with a single parabolic (with Radome) and a small panel standing for 10 years now and we've had some REALLY bad wind the past two years. They are tough to work on near the top though - not much foot room. The the top plate and the rotator plate below it are not made to take a lot of torque imho.
We have about 4 dozen towers, most are less than 80', but there are a few over 200' to our gear and I'd far sooner climb any of them than the only T200 that we have.

LOL - I think climbers hear that a lot... it's easy just don't look down and never climb if that air-raid siren in your head is going full out.... I ignored it once and shoulda died as a result. Other than that: training, equipment, and don't look down or straight up for that matter and stay focused on what you're doing.

I always get a gut feeling within 5 minutes of being on site if I should be climbing the tower or not. I have climbed some real pieces of junk over the years. I have already gone 1/2 way up a few and turned right around and went back down.

You just know it when you put your foot on the first rung that something isn't right? Last year, I got a call to climb up and replace an HDTV antenna on a tower that was made up of those imitation Rohn 20G tower sections. I have no clue who makes them, but they look just like a 20G, only a LOT thinner. It was all rusty and hadn't been serviced in quite a few years and had guys with the wires coming apart on it.

It was only guyed 1 time and it was like 3 sections above the roof line. I refused to climb it! The guy who subbed me out got mad (It's funny?, he climbs stuff all the time, but he was "BUSY" that week, Lol), the customer got all bent out of shape but I didn't care. I got into the truck and left. 5 days later it folded and smashed into the roof. IMAGINE THAT!

I climbed a gold nugget 18ga that was more than 4 sections over the roof line. 7 Sections in total, with a big ass VHF antenna on a 15' mast on top of it. It had No guys, but I was only going to mount at 2 sections over the roof so even though it didn't look good, I decided to go for it... what could go wrong eh ?

I was on the house side of it and just getting to the height when I heard a 'crick' noise - which I think was the bolt on the outside leg sheering (?) - and started to list hard to the outside at the joint just above the roof brace. I was lucky that it happened 'slowly' enough that I slid down the tower with only my lanyard (like a fire pole) about 10' and then jumped/fell backwards onto the peak of the roof as the top 40' peeled over and crashed into the roof of the garage 20' below. Stupid and Lucky to be alive - had I been on the 'outside' it would have went over so fast I would have road it all the way down.

Implemented some very strict rules on gold nuggets and site assessment following that, and every nugget I climb now freaks me out even if it's rock solid.
