Topband: beverage construction

[Jorge Diez - CX6VM]

Hello

 

I was Reading http://www.w8ji.com/beverages.htm to refresh me about
beverages.

 

I am installing  a temporary beverage for next weekend. I will use bare
copper wire, because will be light that the one that have a plastic cover
(liner?)

 

But now I am thinking about the antenna and ground. Why I cannot hang
directly to wood supports and I need to put a insulator on the wooden
supports to put the wire?

 

So what about the two ends wooden supports? How can I tension the wire if I
need to isolate the wire from the wooden supports? 

 

73,

Jorge
