[TowerTalk] How critical is the 120 degree ...

[john at kk9a.com]

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 rotating tower I
believe that a larger anchor distance makes it easier for the guy bearings
to turn.

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 telescope mast 18+18 m = 32 meters.

B) The steel tower height is 31 m - it's a rotating tower - but the 
upper bearing is at 23 m ( leaving 8 meters for the antennas) and the 
lower bearing at 11 meters.

Whats the advise of anchor point distance? Some say, that the 60 % 
(distance for  the tower) should be calculating from the total height 
(31 x 0,6 = 18,6 meters).
Some say, it should be calculating from  the upper bearing (23 m x 0,6 = 
12.8 m)

Whats your opinion?
