1. [TowerTalk] Re: Pull rope twisted in conduit (score: 1)
Author: steve@oakcom.com (Steve Maki)
Date: Sat Aug 2 01:36:34 2003
If you do keep one in there, make it a braided rope rather than a twisted one. Twist ropes love to wrap themselves around anything they come near. Or, as someone else suggested, a smooth piece of THH

2. [TowerTalk] Combo guyed base, free standing tower (score: 1)
Author: steve@oakcom.com (Steve Maki)
Date: Sun Jun 22 22:27:05 2003
It's possible to go much steeper than 70% with a guyed tower, if it's engineered properly. For example, there's a 700' tower near me with guy radius of around 300'. It requires a stronger tower, stro

Someone was probably cutting new port holes with a torch, rather than cutting wheels. The coax jackets are on fire. Not the first time that's happened. Steve K8LX

And yet, if you order specific lengths from the factory and are willing to pay for potted ends (spelter sockets), they will terminate them for you. In fact, spelter sockets are the ONLY termination

5. [TowerTalk] Guyed self-supporters (was "Concrete suggestions") (score: 1)
Author: steve@oakcom.com (Steve Maki)
Date: Wed Apr 16 23:13:35 2003
That makes sense to me - I've often wondered about claims that guy wires will over stress a self supporter, especially without even mentioning guy angles. In order for a self supporter to be a self s

In my very simplified mental model, I'm picturing a 45? upwind guy attached at the top of the tower, a perfectly rigid 100' tower with a 10' face width base, and 1000 lbs of wind force all concentrat

Date: Tue, 01 Oct 2002 01:24:55 -0400
I've seen various breaking strengths quoted for wire rope and aircraft cable, usually slightly less than EHS, but my main concern with using galvanized wire rope for guy wires is longevity. Wire rope

Or just a quick layer of vinyl tape under the heat shrink. It's called a courtesy wrap by some. -- Steve K8LX

I'm trying to get a handle on this concept of PVC jackets not being waterproof, to no avail so far. I can certainly accept that there are materials better suited for direct burial coax jackets but al

One advantage the SteppIR claims is that it can be optimized for a single frequency without having to worry about SWR/gain/FB bandwidth. However, I just played around for a minutes in YO and it appea

Depends. If you are willing to assemble it yourself (on the ground), and your lot permits access to a small crane, it might not be any more expensive. A crane would be in and out of there in an hour

Good luck with that. I had the same thing happen a couple of years ago - the picture tubes on two sets now seem to be permanantly magnetized. I've got a humongous degaussing coil that seems to straig

Hi Steve, It may have worked for you, but the shims do nothing to relieve the twisting torque on the leg, which would be my main concern. I would have nightmares about brace welds ripping out of leg

I like to use an appropriately sized shackle - it makes assembly and disassembly much easier. -- Steve K8LX

Correct. In addition to preventing the 'fold', a thimble or insulator, by holding the wire in a well defined path, prevents wear. I seem to recall W3LPL reporting a guywire failure at the earth ancho

Perhaps. On cell sites, there's a lot of stranded wire used in the ground systems - pretty much everything ABOVE the lower ground bars is stranded. Ground kit leads, interconnections between upper an

Don't scrimp on the concrete though. In average soil it takes much more concrete than one might think to keep the post from slowly leaning over when under constant tipover force of a few hundred poun

Hi Bill, I know you are in favor of hiring PEs for everything, and that's a good course, but not necessarily the only valid one. Sometimes overkill is cheaper than a PE, and just as comforting. I've

A fairly easy way to accomplish this shape - I just did one last year - is as follows: 1) Dig a straight sided hole, insert rebar cage and pour the pad. 2) Set a light form for the pier (Sonotube wor

Most any maintenance I can think of would require loosening and dropping the guy in towards the tower anyway, so I'm not sure what good it will do you, but the Phillystran factory will make up guy li
