[TowerTalk] Professional HF curtain arrays

[John E. Cleeve]

Good afternoon,

 

I wonder, are there any in the group with professional experience of
erecting the wire curtain arrays, suspended between tall towers, as used at
professional SW BC stations? If there are, then may I ask what method is
used to connect the feeders to the antenna elements, in order to eliminate
any "flexing" movement between the two, caused by varying wind pressure,
which may then lead to metal fatigue and fractures and failure? 

 

I have trawled through all the information I can find, in books and on the
internet, but without success. I can only think that the entire wire curtain
array must be suspended under such tension, that it must behave as a rigid
structure. I would be grateful if any of the group can supply the answer. A
link to an appropriate text book would be much appreciated. 73, John. G3JVC
