Hi ... I'm sure these topics have been discussed earlier, but could not find any thread ..... Sri ... We are at our club erecting two towers. A rotating steel tower being 31 m high and a aluminium te

To be safe, do not rely on opinions.  Get your advice from either the manufacturer or a registered professional. 73 Keith NM5G On Tuesday, July 27, 2021, 02:49:25 AM CDT, Jari Jussila <jari.jussila@o

Hi Jari, I agree that, as a goal, you should always follow the manufacturers instructions. However, in some installations that may not be possible due to topography and other reasons. Both my towers,

In the U.S., the standard guy anchor distance is 80% of the tower height but I have heard in Europe 60% is more common. Is that correct? I have no answers to your questions but if you are using a rot

The steeper the angle (smaller angle to tower) the more tension is needed to provide the same horizontal restoring force at the connection of the guy to the tower. The needed horizontal force is dete

The first question seem like a rather simple vector analysis task to me.  Generate a simple model for the manufacturer's recommendations for included angles, distance from tower, and guy wire tension

Both cases are fairly simple vector analyses. Deviating from the 120 degree spacing will result in increased tension on some of the guys, as well as vertical load on the tower.. You can calculate tha
